Auckland turns a corner as Wellington faces structural decline, new analysis warns

New Zealand's property market is splitting along lines that have little to do with interest rates and everything to do with farm incomes and structural economic shifts, according to independent economist Tony Alexander (pictured) writing for OneRoof.

The clearest illustration of this divergence is Southland, where rising dairy returns have pushed average house prices up 1.7% over the three months to May and 7.5% annually. Auckland, by contrast, slipped 0.2% over the quarter and 1.5% over the year, while Wellington fared worse still, falling 0.7% for the quarter and 2.6% year-on-year.

Canterbury sits between these extremes, posting quarterly growth of 1.2% and annual gains of 3.2% — buoyed by a strong farming base, solid population growth in Christchurch, and what Alexander describes as firmer upward economic momentum.

The most recent REINZ data reinforces the picture for Auckland and Wellington in particular. According to REINZ's April 2026 House Price Index, Auckland's HPI fell 2.8% annually and Wellington's by 2.5%, while Southland posted an 8% annual rise to a record high.

Auckland is turning a corner

Alexander sees the current Auckland underperformance as temporary. The city is being held back primarily by an overhang of townhouses that buyers are not particularly eager to purchase — a drag he expects to persist well through next year. But several tailwinds are building. The City Rail Link is due to open later in 2026, foreign student numbers are recovering, and tourism is improving.

Higher farm incomes in the Bay of Plenty, Waikato, and Northland will eventually flow through to Auckland as rural wealth finds its way into the central city.

"The central city is finally enjoying some upward momentum, and that will continue once the City Rail Link opens later this year," Alexander said.

Cotality NZ chief property economist Kelvin Davidson echoed that cautious optimism in May.

"There have been hints that property values in some parts of Auckland may have started to turn a corner in the first few months of 2026," Davidson said. "But the data remains patchy, and the bigger picture is that values across the board are still lower than a year ago."

Wellington's structural decline has further to run

Wellington's outlook is considerably bleaker. Alexander frames the capital's downturn not as a cyclical correction but as a structural repricing — a long-overdue adjustment following years of inflated demand from the Lord of the Rings film industry and government spending that has since unwound.

A looming water infrastructure crisis is adding to the pressure. The average annual water bill is currently projected to rise from around $2,400 this year to $7,100 by 2036 — a burden that Alexander says risks driving further population loss, particularly from older residents and younger households. He points to a historical parallel: between 2007 and 2015, Wellington Region house prices rose just 4.6% while national prices climbed 32.3%.

"A repeat of that relative performance may well be underway again," Alexander said.

Internal migration within the wider Wellington region — towards Lower Hutt, Upper Hutt, Porirua, and the Kapiti Coast — is likely, with spillover into Manawatu-Whanganui as roading infrastructure expands.

The macro picture is not offering much relief. ASB expects house prices to remain flat in 2026 with the balance of risks tilted lower, while Westpac is forecasting a modest 1% national price fall over the year — with mortgage rates adding to the pressure as upward movement is already under way before the RBNZ has made any official cash rate moves.
