Council rates for 2026/27 are being locked in right now, and the headlines are doing their usual thing, reporting each town’s number on its own. Put them side by side and a clearer story appears. In the big cities the rises are actually coming in lower than the eye-watering figures councils forecast a year ago. The catch is that the relief is uneven, and one cost is driving almost all of the pain that remains. Water.
We compiled the 2026/27 increases from the annual plans councils are adopting before 30 June. The pattern is a split screen. Metros are trimming their rises while the districts carrying big water bills are being pushed the other way.
The big-city rates rises for 2026/27
Auckland has adopted a record 7.9 percent increase, lifting the average household bill from $4,057 to $4,378, a rise of about $321. Almost all of that is the roughly $235 million a year it now costs to run the City Rail Link, which opens later in 2026. On top of the rates rise, Auckland water charges go up 7.2 percent from July.
Elsewhere the story is restraint. Wellington City has cut its draft increase to 5.8 percent, down from 7.4 percent put out for consultation and an originally planned 12.7 percent. Christchurch’s draft sits near 8 percent overall, around 7.4 percent for residential ratepayers. Dunedin is proposing 10.5 percent, and the Greater Wellington regional council has settled on 9.7 percent, itself cut back from the 13.3 percent its long-term plan had pencilled in.
How your council compares
| Council | 2026/27 rise | Status |
|---|---|---|
| Wellington City | 5.8% | Draft |
| Christchurch | ~8% (7.4% residential) | Draft |
| Auckland | 7.9% | Adopted |
| Greater Wellington (regional) | 9.7% | Adopted |
| Dunedin | 10.5% | Proposed |
| Waitaki (district) | up to ~22%, being curbed | Proposed |
Even the lower numbers are well ahead of inflation, which is running near 3 percent. A 5.8 percent rise is restraint only by the standards of the past three years, when rates in several cities climbed more than 40 percent all up. What has changed in 2026/27 is that councils blinked at their own forecasts and trimmed. The question is how long they can keep trimming while the bill underneath keeps growing.
Why water is now the biggest driver
Dunedin shows the split better than any speech could. Its proposed 10.5 percent breaks into two very different halves, about 6.9 percent for everything the council normally does and about 16.7 percent for water alone. The ordinary business of running a city is rising roughly in line with costs. It is the pipes that are blowing the budget.
The reason is the Government’s Local Water Done Well policy. The earlier plan to pool water assets into large regional entities was scrapped after the 2023 election, which means most councils now have to finance the renewal of their own ageing pipes, treatment plants and reservoirs on their own books. Decades of underinvestment are coming due at once, and the cost lands on the rates bill.
That is why the steepest rises are not in the big cities at all. Waitaki, a district of about 23,000 people, consulted on 19 percent and at one point voted for 22 percent, driven by a $37 million water programme, before scrambling for savings to bring it down. A small ratepayer base carrying a large water upgrade has nowhere to hide. The metros can spread the cost over hundreds of thousands of households. A rural district cannot.
Where rates already sit
This year’s increases land on bills that already vary enormously. The Taxpayers’ Union Ratepayers’ Report 2026, which draws on councils’ 2023/24 annual reports rather than the coming year, put the average residential rates bill at about $3,386, up $451 on the year it covered. The spread is the striking part. Porirua topped the table at $5,591, while Ōtorohanga District charged the least at $2,554, a gap of well over 100 percent for what is nominally the same service.
Those are historical figures, a year or two behind the 2026/27 rises above, but they make the point that there is no single New Zealand rates bill. What you pay depends heavily on which line on a map your house sits inside.
We have written before about how rates have outpaced inflation for years, and about the separate Auckland water bill rising 7.2 percent from July. The 2026/27 round is where those pressures meet on a single invoice.
When the figures are final
Most of the numbers above are still draft or proposed. Councils adopt their final 2026/27 annual plans by 30 June, so a few will shift in the next few weeks as elected members hunt for last savings. The direction, though, is set. Headline rises are easing in the cities, water is the force that will not ease, and the districts with the smallest shoulders are carrying the heaviest pipes.
Quick answers
How much are Auckland rates going up in 2026?
Auckland has adopted a 7.9 percent rates increase for 2026/27, lifting the average household bill by about $321 to $4,378. Most of the rise pays to run the City Rail Link. Water charges rise a further 7.2 percent from July.
Why are my rates rising so much?
The biggest driver is water. Under Local Water Done Well, councils must fund the renewal of their own pipes and treatment plants, after decades of underinvestment. Debt servicing and, in Auckland, the City Rail Link add to the bill.
When are 2026/27 rates confirmed?
Councils adopt their final 2026/27 annual plans by 30 June 2026. Many of the figures circulating now are draft or proposed and may change slightly before adoption.
As at June 2026. Sources, councils’ 2026/27 annual plans (Auckland Council, Wellington City Council, Christchurch City Council, Dunedin City Council, Greater Wellington and Waitaki District Council), and the Taxpayers’ Union Ratepayers’ Report 2026 for historical average rates. Figures marked draft or proposed are adopted by 30 June 2026.
