Do I have to let police search my car, house or phone in New Zealand?

Last updated 17 May 2026. This is general information, not legal advice.

This is one of the most-searched legal questions in New Zealand, and most of the answers you find online are wrong, because they are American. New Zealand has a very different police search regime to the United States, and the wrong assumptions can either get you in trouble (by resisting a lawful search) or cost you (by consenting to one you did not have to).

This guide explains, in plain English, what police can and cannot do in 2026 when they want to search you, your car, your home or your phone. It also covers what you have to tell them, what you can refuse, and what to do if you think a search has crossed the line. It is general information, not legal advice. Every claim ties back to the Search and Surveillance Act 2012, the New Zealand Bill of Rights Act 1990, and current police policy. If you are facing an actual police interaction right now and have a moment, the most important thing you can do is contact the free Police Detention Legal Assistance lawyer service on 0800 919 257 before you say or sign anything.

The starting point, you have a right against unreasonable search and seizure

Section 21 of the New Zealand Bill of Rights Act 1990 gives every person the right to be secure against unreasonable search or seizure, whether of the person, property, correspondence or otherwise. That right is the foundation of every search law in New Zealand. Police cannot search you, your car, your home or your phone unless one of three things is true:

• You consent
• They have a warrant
• They have a specific statutory power to search without a warrant

If none of those three applies, the search is unlawful, and any evidence found can potentially be ruled inadmissible in court. The Bill of Rights does not, on its own, stop the search happening in the moment, but it shapes how the law operates and how courts review what police have done.

The key practical point. Many police searches in New Zealand happen by consent, not because police have a statutory power. If you understand when you can and cannot say no, you can avoid a lot of trouble.

Consent searches, the most important thing to understand

Police regularly ask “do you mind if I have a look in your bag?” or “can I check the car?” or “can I have a quick look at your phone?” These are consent searches. You are not legally required to agree to them.

Under section 91 of the Search and Surveillance Act, before asking for your consent to a search, a police officer must:

• Tell you the purpose of the proposed search
• Tell you that you have the right to refuse
• Tell you that any evidence found can be used in court against you

If the officer does not do these three things, your “consent” is not valid and any search that follows is unlawful.

The catch most people fall into is that consent feels mandatory in the moment. You are nervous, the officer has uniform and authority, and saying “no” feels like an admission of something. It is not. Politely declining a consent search is your legal right. The right answer is something like “I’d prefer not to consent to a search, officer. Am I free to go?” If the officer has no other legal basis to search, that is the end of it.

You can also withdraw your consent at any time. If you said yes and then changed your mind partway through, you can say “I withdraw my consent” and the search must stop, unless the officer has by then found something that gives them a separate legal power to continue.

The cases where consent is invalid even if you say yes:

• Under section 95 of the Act, a person under 14 cannot validly consent to a search of a place, vehicle or other thing (a police officer cannot rely on the consent of a child to enter a property)
• A person under significant duress or intoxication may not be capable of giving free consent
• Consent obtained by deception (the officer misrepresents why they want to search) is invalid

Can police search me as a person

It depends on whether you have been arrested, and what the officer suspects.

If you have not been arrested or detained, police generally cannot search you unless they have specific statutory grounds. The main warrantless grounds for searching a person in a public place are:

• Reasonable grounds to suspect you have a controlled drug on you (section 22, Search and Surveillance Act)
• Reasonable grounds to suspect you have a firearm or other dangerous weapon
• Reasonable grounds to believe you have evidence of an offence carrying 14 years or more imprisonment (section 16)
• You are in a public place where there is a liquor ban and they are searching for alcohol (under the local council bylaw)
• You are entering or leaving a customs-controlled area such as an airport or port

Outside those grounds, an officer needs your consent to search you, or a warrant.

If you have been arrested, the position changes. Section 88 of the Search and Surveillance Act allows police to search you without a warrant if they have reasonable grounds to believe you have on you anything that may harm someone, may be used to escape, or may contain evidential material relating to the offence you were arrested for. This is called a search incidental to arrest, and it is broad.

If you have been taken into custody, section 11 allows a search before you are locked up. This is a routine custody search.

For strip searches the threshold is higher. Strip searches must be justified, must be carried out by an officer of the same gender, and must be conducted in private. If a strip search is carried out without proper grounds, it is a separate unlawful act.

Can police search my car

This is one of the most common scenarios and the law is more permissive than people expect.

Police can search your car without a warrant if they have reasonable grounds to suspect that the car contains evidence of certain offences. The main grounds are:

Drugs. Under section 20 of the Search and Surveillance Act, police can stop and search your vehicle without a warrant if they have reasonable grounds to suspect there is a controlled drug in it that you are committing an offence in relation to. This is the most common warrantless search ground in everyday traffic stops. Reasonable suspicion is a lower bar than belief, but it still has to be more than a hunch. The smell of cannabis from the car, drug paraphernalia visible on the dashboard, or your behaviour combined with other indicators can supply it. The officer must tell you the object of the search before conducting it (section 9).

Firearms or other weapons. Under section 18 of the Act, police can search a vehicle without a warrant if they have reasonable grounds to suspect there is a firearm or other dangerous weapon in it being unlawfully carried.

Serious offences. Under section 17, police can search a vehicle without a warrant if they have reasonable grounds to believe (a higher threshold than suspect) that the vehicle contains evidence of an offence carrying 14 years or more imprisonment, and that immediate action is needed to prevent loss of the evidence.

Stolen property. Under section 30, police can search a vehicle without a warrant for property they suspect to be stolen, if they reasonably believe it is in the vehicle and immediate action is needed.

Other warrantless powers. A range of more specific grounds exist for things like the proceeds of crime, search incidental to arrest, and gang-related offences under recent amendments to the Act.

If police have one of these statutory grounds, they do not need your consent. They can search the car whether you agree or not. They are required to tell you what they are searching for.

If they do not have one of these grounds, they need your consent. Most roadside searches happen by consent. The officer asks “do you mind if I have a look in the boot?” and most people say yes because saying no feels confrontational. You do not have to say yes.

A practical sequence if you are asked to consent to a car search:

• Ask “Am I being detained or am I free to go?”
• If the officer says you are free to go, you can leave
• If the officer says you are being detained or that they have a power to search, ask “Under what law are you searching the car?” or “What is the object of the search?”
• If the officer cites a specific power (drugs, weapons, stolen property), the search is happening whether you consent or not. Cooperate calmly. Do not obstruct. Do not consent. Make a note of what was said and what was searched
• If the officer is asking for consent, you can decline politely. “I’d prefer not to consent to a search of the car, officer”

You are not obligated to explain why you are declining, and your refusal cannot itself be used as grounds for the officer to search.

Can police search my house

Your home gets the strongest protection in New Zealand law. Police generally cannot enter or search your home without one of these:

A search warrant. A warrant issued by a judge or other issuing officer (a registrar or authorised JP) under section 6 of the Search and Surveillance Act. The officer must show you the warrant before entering, or as soon as practicable after entering. You have the right to see the warrant and read it.

A valid warrant must specify:

• The address of the place to be searched
• The offence the warrant relates to
• The items being searched for
• The name of the issuing officer and the date

You can ask to see the warrant and read it before they enter. If the warrant is plainly defective (wrong address, expired date, no signature) you can point that out. You cannot physically resist the entry but you can preserve your position for a later challenge.

Specific statutory powers without a warrant. Police can enter your home without a warrant in limited situations:

• To prevent an offence likely to cause injury or serious damage to property, under section 14
• To execute an arrest warrant for someone in the house, under section 7
• To arrest someone they have reasonable grounds to believe is in the house and has committed an imprisonable offence, under section 8
• To find and avoid loss of evidential material relating to an offence carrying 14 years or more imprisonment, under section 15
• In an emergency, where they need to enter to respond to an immediate risk to life or safety

These are narrower than people think. Section 8 in particular only authorises entry to find a person, not to search for things, and the Court of Appeal in Court v R [2020] NZCA 76 held that a section 8 entry is not the basis for a general search for stolen property.

Your consent. You can let them in. You do not have to. If you do, you can put conditions on the search (“you can come in but only the lounge” or “you can stay for 20 minutes”) and you can withdraw your consent at any time. The search must stop unless they have by then found something giving them a separate power to continue.

If officers turn up at your door and ask to come in:

• You can ask why they are there
• If they say they have a warrant, you can ask to see it
• If they say they do not have a warrant, you can decline to let them in
• If you let them in for one purpose, they cannot use that as cover to search the whole house

You should not lie to police, and you should not physically obstruct them. But you do not have to invite them in and you do not have to consent to a search. “I’d rather you didn’t come in. Is there something I can help you with from here?” is a perfectly lawful response.

Can police search my phone

This is where the law is unsettled and the practical answer often comes down to whether you have been arrested.

Without arrest, no. Police cannot search your phone without your consent unless they have a warrant or a specific statutory power. They cannot make you unlock your phone just because you are talking to them on the street.

With arrest, the position changes significantly. Section 88 of the Search and Surveillance Act allows police to search items in your possession at the time of arrest if they have reasonable grounds to believe the item contains evidential material relating to the offence you were arrested for. Section 125(1)(l) of the Act explicitly extends search powers to “any computer system or other data storage device” found at the place. Modern phones fall within this definition.

In practice, this means that if you are arrested for a drug offence and you have a phone on you, police can search it for messages, photos and contacts relating to the drug offence. They are not supposed to range freely through everything on the phone, but the boundary is contested in case law.

Can they compel you to unlock it? This is the most contested question.

Section 130 of the Search and Surveillance Act allows police, in a search carried out under a warrant or warrantless power, to require a person with knowledge of a computer system to provide reasonable assistance, including access information. Failure to comply without reasonable excuse is an offence carrying up to three months imprisonment.

The legal position is that section 130 can be used to compel you to unlock a phone that police are lawfully searching. The “no self incrimination” right has generally been understood to apply to the content revealed by unlocking, not to the act of unlocking itself. This is similar to the position in the United Kingdom and different from the United States.

In practical terms:

• You can decline to unlock the phone, but if you do so when section 130 applies, you may commit a separate offence
• The safer course if police demand you unlock a phone is to ask for the lawful basis (warrant or specific warrantless power), comply if the basis exists, and challenge the search later if it was unlawful
• A lawyer should be involved in any case where this is happening. Use the free Police Detention Legal Assistance line on 0800 919 257

Biometric unlock (fingerprint, face). Police can use reasonable force to compel a biometric unlock if they have a valid search power. Many criminal lawyers advise turning biometric unlock off and relying on a passcode if you have concerns, because the legal protections around compelled passcode disclosure are slightly stronger than around physical biometric features.

What about Customs at the airport

Customs officers have much broader powers than police, and the rules at the border are different.

Under the Customs and Excise Act 2018, Customs officers can:

• Search your baggage and personal items without a warrant or reasonable suspicion at the border
• Search electronic devices at the border, including phones, laptops and tablets
• Require you to provide passwords, passcodes or other access information for electronic devices

Refusing to unlock a device at the border is an offence carrying a fine of up to $5,000. Unlike with police, the threshold for Customs to demand access is “reasonable cause to suspect that the device contains evidence of relevant offending”, which is a lower bar than a normal search.

The practical advice for travellers who are concerned about phone searches at the border:

• Travel with a clean device or a device that does not have the data you are concerned about
• Sign out of cloud accounts before arriving so a device search does not extend automatically to your full account history
• Know that powering off a phone before arrival forces a full passcode entry on next boot, which has slightly different legal treatment than a biometric unlock

What do I have to tell police

This is one of the most misunderstood areas in New Zealand law.

The general rule. You are not required to answer questions from police. Section 23(4) of the Bill of Rights Act gives every person arrested or detained for any offence the right to refrain from making any statement and to be informed of that right.

But there are specific situations where you must provide identifying information:

If you are driving. Under the Land Transport Act, you must give police your name, date of birth and address. If there has been a crash, you must also provide your licence and vehicle details. Refusing is itself an offence.

If you are suspected of being under 18 and consuming alcohol. You must give your name, date of birth and address.

If you are carrying or have used a firearm. You must give your name, date of birth and address.

If you have been arrested. You must give your name, date of birth, address and occupation. You do not have to answer any other questions.

Outside these specific cases, you are generally not required to give your name or any details to police. You can ask “Am I being detained, or am I free to go?” If you are free to go, you can decline to give your details and walk away.

Do not give false information. Even in situations where you are not required to give your details, lying to police can be a separate offence (obstructing or perverting the course of justice). Either refuse to answer, or tell the truth. Do not invent.

The right to silence and the right to a lawyer

The single most important thing to know about a police interaction in New Zealand is that you have the right to remain silent and the right to consult a lawyer.

Under section 23 of the Bill of Rights Act, anyone arrested or detained has the right:

• To be informed at the time of the reason for arrest or detention
• To consult and instruct a lawyer without delay and to be informed of that right
• To remain silent and to be informed of that right
• To be charged promptly or released
• To have the validity of the arrest determined by habeas corpus

If you are arrested or detained, your first words should be “I want to speak to a lawyer.” Then say nothing else about the matter under investigation. The free Police Detention Legal Assistance scheme provides a lawyer on the phone 24/7 for anyone in custody. The number is 0800 919 257. The call is free, the consultation is confidential, and using it does not mean you have something to hide. It is the standard practical advice from every criminal lawyer in New Zealand.

What “saying nothing” actually looks like:

• “I understand. I want to speak to a lawyer before I answer any questions.”
• “On my lawyer’s advice, I am not making a statement at this time.”
• “I’m exercising my right to silence.”

You can repeat these phrases as often as needed. Officers can keep asking. You can keep declining. The right to silence does not run out, and it does not get weaker the longer you exercise it.

People hurt their own cases by trying to “explain” away suspicion to a sympathetic-seeming officer in the moment. Almost every criminal lawyer can point to clients who would have been fine if they had stayed quiet and let the lawyer handle the conversation.

Can I record the police

Yes. In a public place, you have the right to film or photograph anyone including police officers, without their consent. Police are doing a public function and have no expectation of privacy while doing it.

On private property, you can film with the consent of the property owner. If it is your own property, you can film freely.

There are limits. You cannot obstruct police while filming. You should keep a reasonable distance and avoid interfering with what they are doing. If an officer asks you to step back, step back, but keep filming.

Recording can be useful evidence in a later complaint or challenge. The footage establishes what was actually said and done, which is invaluable when the issue is whether a search was lawful or whether consent was properly obtained.

What if I think the search was unlawful

If a search has happened and you believe it was unlawful, you have several options.

Make detailed notes immediately. Date, time, location, names and numbers of officers, what was said, what was searched, what was seized. Memories fade fast and the court will weigh contemporaneous notes more heavily than reconstructed recollections.

If you were charged, challenge the search through your lawyer. Under section 30 of the Evidence Act 2006, evidence obtained from an unlawful search can be excluded from a criminal trial. The court weighs the seriousness of the breach against the importance of the evidence and the seriousness of the offence. Successful exclusions happen regularly in New Zealand courts.

Complain to the Independent Police Conduct Authority. The IPCA is the independent body that investigates complaints about police conduct. You can file online or call 0800 503 728. The IPCA cannot order compensation but it can find police acted unlawfully and recommend changes.

Civil claim for damages. Under the Bill of Rights Act, you can sue police for damages where an unlawful search has caused you loss. Awards have been made for damaged property, unlawful detention, and breach of the right against unreasonable search and seizure. Talk to a lawyer about whether your case is strong enough to justify the cost.

A simple decision tree for a police interaction

If you are stopped or approached by police:

One. Ask “Am I being detained, or am I free to go?” This forces the officer to clarify their legal position.

Two. If you are free to go, you can leave. You do not have to give your name or answer questions (unless one of the specific exceptions above applies).

Three. If you are being detained but not arrested, ask why. The officer must tell you. You do not have to answer questions but you may have to give your details depending on the reason.

Four. If you are arrested, give your details (name, DOB, address, occupation) and then ask for a lawyer. Say nothing else about the matter under investigation. Call 0800 919 257 if no lawyer is offered to you.

Five. If asked to consent to a search, you can decline politely. “I’d prefer not to consent to a search, officer.”

Six. If a search is happening under a statutory power, do not obstruct it. Cooperate calmly, take notes, do not consent verbally, and challenge it later if needed.

Seven. Make notes as soon as you can. Time, place, what was said, what was searched, what was found.

Free help when you need it

You do not have to navigate this alone. Several free services exist.

• Police Detention Legal Assistance on 0800 919 257 is a free 24-hour line that connects anyone in police detention to a lawyer
• Community Law Centres provide free legal advice for people with limited means
• The Citizens Advice Bureau provides general guidance
• The Independent Police Conduct Authority takes complaints about police conduct
• The New Zealand Law Society can refer you to a criminal lawyer in your area

The takeaway

The biggest single mistake New Zealanders make in police interactions is assuming they have fewer rights than they do, because the rules they have seen on television are American. New Zealand law is different. You have a real right against unreasonable search. You have a real right to silence. You have a real right to a lawyer, free, before you say anything. Most consent searches that happen here happen because people did not know they could say no.

The second biggest mistake is the opposite. Assuming you have more rights than you do, and obstructing a lawful search. Police have broad statutory powers to search cars for drugs, search people for weapons, enter homes with warrants, and search phones and devices in possession at arrest. If they have one of these powers, the search is happening, and resisting it is its own offence.

The practical answer in almost every uncertain interaction is the same. Be calm. Be polite. Ask what is happening and on what basis. Decline to consent to searches you do not have to consent to. Decline to answer questions you do not have to answer. Ask for a lawyer. Make notes. Sort it out later, with proper advice, not on the side of the road or at a doorstep.

If you take only one number with you from this guide, take this. 0800 919 257. Free lawyer, any time of day or night, if you are in police custody. It might be the most useful number you ever save.

Frequently asked questions

Do I have to let police search my car in New Zealand

Only if police have a warrant or a specific statutory power, such as reasonable grounds to suspect drugs, firearms or stolen property. Outside those grounds they need your consent, and you are not legally required to give it. You can politely decline a consent search of your vehicle.

Do I have to give my name and address to police in New Zealand

Only in specific situations. You must give your name, date of birth and address if you are driving, if you are suspected of being under 18 and drinking, if you are carrying or have used a firearm, or if you have been arrested. Outside those specific cases, you can decline to give your details and walk away if you are free to go.

Can police make me unlock my phone in New Zealand

If police are conducting a lawful search of your phone under a warrant or warrantless power, section 130 of the Search and Surveillance Act can compel you to provide reasonable assistance including the passcode. Failure to comply without reasonable excuse carries up to three months imprisonment. If police are not conducting a lawful search, you do not have to unlock it.

Can police enter my home without a warrant in New Zealand

In limited circumstances. Police can enter without a warrant to prevent an offence likely to cause injury or serious damage, to arrest someone they reasonably believe is inside, to prevent loss of evidence for a serious offence (14+ years imprisonment), or in an immediate emergency. Outside those situations, they need a warrant or your consent.

What should I say if police ask to search my bag

You can politely decline. “I’d prefer not to consent to a search, officer. Am I free to go?” Police must tell you the purpose of the search and that you have the right to refuse before asking for consent. Your refusal cannot itself be used as a ground to search.

Can I record police officers in New Zealand

Yes. In a public place you can film police officers without their consent. Police have no expectation of privacy while performing a public function. You should not obstruct them, but you can keep a reasonable distance and continue filming. Footage often makes the difference in a later complaint or court challenge.

What does reasonable suspicion mean for a police search

Reasonable suspicion is a lower bar than reasonable belief but it has to be more than a hunch. The officer must be able to point to specific facts (the smell of cannabis, visible paraphernalia, your behaviour combined with other indicators) that an objective observer would also see as suspicious. A vague feeling or appearance alone is not enough.

Can Customs search my phone at the airport in New Zealand

Yes. Customs officers have much broader powers than police at the border. Under the Customs and Excise Act 2018 they can require you to unlock a phone, laptop or tablet if they have reasonable cause to suspect it contains evidence of relevant offending. Refusing carries a fine of up to $5,000.

Can I withdraw consent after agreeing to a police search

Yes. You can withdraw consent at any point during the search by saying clearly that you withdraw your consent. The search must stop unless police have by then found something that gives them a separate statutory power to continue. State the withdrawal out loud and, if possible, in front of a witness or on camera.

What happens if police conduct an unlawful search in New Zealand

If you were charged, your lawyer can apply to exclude the evidence under section 30 of the Evidence Act 2006. Whether the evidence is excluded depends on the seriousness of the breach, the importance of the evidence and the seriousness of the offence. You can also complain to the Independent Police Conduct Authority on 0800 503 728, or bring a civil claim for damages under the Bill of Rights Act.

What is the free Police Detention Legal Assistance number in New Zealand

0800 919 257. The Police Detention Legal Assistance scheme provides a free lawyer 24 hours a day, seven days a week, to anyone in police detention. The call is free, the consultation is confidential, and asking for a lawyer is the standard advice from every criminal lawyer in New Zealand. Save the number in your phone.

Can police stop me from filming them in a public place

No. Police cannot lawfully stop you filming them in a public place, although they can ask you to step back if you are obstructing them. If an officer asserts you cannot film them, you can politely point out that police performing a public function in a public place have no expectation of privacy. Keep filming if it is safe to do so.
