Auckland’s northwest busway has cleared the last legal hurdle standing between it and a construction site, but almost none of the money to build it has been committed.
Infrastructure Minister Chris Bishop announced on Friday that the North-West Rapid Transit project, a dedicated bus corridor running alongside State Highway 16, has been granted fast-track approval. It is the 33rd project to get through the process set up under the Fast-track Approvals Act.
The approval covers a busway between Brigham Creek and the Auckland city centre, seven rapid transit stations, one park and ride facility at Brigham Creek Rarawaru, and connections into the surrounding local bus and road network. The New Zealand Transport Agency lodged its application in December 2025, and the Government says approval took less than five months from the day the independent expert panel was appointed.
“This project will provide faster, more frequent and reliable public transport for Aucklanders living in the north-west, one of the city’s fastest-growing areas,” Mr Bishop said.
“By 2051, roughly 100,000 more people are expected to call the north-west home. Once completed, the project will have the ability to move up to 9,000 passengers per hour in each direction and provide a reliable 25-minute journey from Brigham Creek to Auckland City Centre.”
He also pointed to the existing Western Express bus service as evidence the demand is already there. “The strong demand for public transport in the north-west is already clear. The WX1 has recorded more than 1.1 million passenger trips in the 12 months to May 2026, exceeding forecasts by around 40 per cent,” he said.
What the decision does not do is pay for anything. Consents and designations settle the legal question of where the busway can go and under what conditions. They do not put a single bus lane on the ground. NZTA’s own project page is blunt about it, saying staged construction may begin from 2027 subject to funding and approvals, and that securing approvals across the route “will help keep future delivery options open and allow work to progress when funding is available”.
That is the real story of Friday’s announcement. The Government has bought the project a permanent legal right of way through one of the most built-up corridors in the country, which is not a small thing, and left the funding decision to whoever is in office when each stage comes up.
What is funded so far is modest by comparison. The first phase of Westgate Te Waiarohia station opened in August, giving northwest bus services a proper hub for the first time. Detailed design is under way on the first phase of the Brigham Creek Rarawaru station and park and ride, which NZTA says is funded for delivery with construction expected to begin in 2027. Everything after that depends on money that has not been allocated.
NZTA has set out the order it wants to build in. Stage one is the Brigham Creek park and ride and station plus a station at Lincoln Road Wai o Pareira. Stage two is a separated two-way busway from Brigham Creek to Te Atatū, with stations at Royal Road Mānutewhau and Te Atatū Ōrangihina and the second half of Westgate. Stage three is the stations at Point Chevalier and Western Springs and the busway between Waterview and the city centre, which is the expensive end.
Stuff reported the decision on Friday under the headline “Green light for $4.9b Auckland busway, but 20-year build lies ahead”, putting the full cost at $4.9 billion and noting the expert panel granted resource consents and approved designations for the whole corridor. On that timeline, a child starting school in the northwest this year would be finishing a university degree before the last station opened.
The case for building it is not really in dispute. Transport blog Greater Auckland, working through the fast-track application in February, found the busway would cut the trip between Westgate and the new Karanga-a-Hape station to about 22 minutes, saving up to 15 minutes on the current WX1 service. More useful than the average saving is what happens to reliability. The application put current travel-time variability at about 14 minutes in the morning peak and 25.5 minutes in the evening, and expected the busway to pull that back to between two and four minutes across the day.
The capacity figure is the one worth holding onto. Nine thousand passengers an hour in the peak direction is roughly what four lanes of motorway traffic can shift, in a corridor two lanes wide. The Northern Busway on the North Shore, which nobody now argues was a mistake, carries about 7.7 million boardings a year. NZTA’s modelling has the northwest corridor reaching 5.4 million weekday boardings a year by 2051.
The timing is not accidental. The City Rail Link opens on 13 September, nine days from now, and Mr Bishop tied the two together directly. “Once fully completed, the Northwest Busway will be a transformational piece of infrastructure for northwest Auckland and, combined with the opening of the City Rail Link, shows this Government’s commitment to improving transport infrastructure across the city,” he said.
With the general election on 7 November, voters in Te Atatū, Kelston, Upper Harbour and the new suburbs around Whenuapai and Red Hills now have a project with every legal box ticked and a funding line that runs out after 2027. Which party commits money to stages two and three, and how fast, is a fair question to put to candidates on the doorstep. If you want to work out where the parties sit on transport spending and everything else, our voting tool lets you compare their positions.
The fast-track scoreboard now sits at 33 projects approved by expert panels, 18 more with panels appointed, and 68 progressing through the system in total. Another 149 projects are listed in the Act and could apply. On average, decisions on substantive applications have taken 118 working days once officials confirm an application is complete.
Do you think the northwest busway should be funded ahead of other Auckland transport projects, or has the city already committed to too much at once? Leave a comment below and tell us what you would build first.
