The years it takes to buy a home, 2001 to 2026

The 2001 baseline — almost ordinary

The story has to start with how unremarkable New Zealand housing affordability looked at the start of the century. In March 2001, a household earning the national median needed 4.6 years of total household income to buy the national median home. Auckland sat at 5.1. Wellington was at 4.6, Christchurch at 4.8, Hamilton at 4.6, Dunedin at 3.4, Invercargill at just 2.2 — a number that today looks like a clerical error. The national multiple had been roughly flat at 3.5 to 4.5 for most of the 1990s.

The numbers were not low because incomes were high. Median weekly earnings in 2001 were around $530, which in today’s terms is about $850. The numbers were low because the median home cost around $170,000 nationally and about $245,000 in Auckland — figures that bore some relation to what a household earning ordinary money could finance with a 30% deposit and a 25-year mortgage. The rule of thumb — three to five times income, with one income paying for it — still mostly worked.

The first big boom, 2003 to 2007

The first sustained departure from the historical range happened between 2003 and 2007. House prices roughly doubled in most centres over that four-year stretch. Wages did not. The national median-multiple climbed from 4.6 to 7.0; Auckland from 5.1 to 7.6; Tauranga, the fastest mover, from 6.5 to 9.5 by late 2007. Wellington crossed five times income in 2003 and never returned. The same is true of Hamilton, Tauranga, Nelson and Napier.

The drivers were a mix of easy credit, the rise of property as an investment asset class, rural-residential migration, and a population that was finally growing again after a decade of net emigration. The Reserve Bank lifted the OCR from 5% to 8.25% between 2004 and 2007 trying to slow the market down. House prices kept climbing anyway, because the credit was coming from offshore wholesale markets, not from domestic deposits, and the OCR was no longer the binding constraint on mortgage rates.

The GFC and the pause that wasn’t, 2008 to 2011

The global financial crisis arrived in mid-2008 and the bank funding markets froze. Mortgage rates spiked briefly above 9%; sales volumes collapsed; prices flatlined or fell slightly through 2009 and into 2010. The national median multiple drifted down from 7.0 to 6.4. Auckland dipped from 7.6 to about 7.0. It looked, briefly, as though the market might revert toward something more normal.

It did not. The Reserve Bank cut the OCR from 8.25% to 2.5% over the year from July 2008 to April 2009 — the most aggressive rate-cutting cycle in the Bank’s history at that point. Mortgage rates followed down. By 2011 the median multiple was climbing again, and by mid-2013 it had passed the previous 2007 peak.

Auckland breaks away, 2013 to 2016

From 2013 onward the city that drove the national story was Auckland. Auckland’s median multiple jumped from 7.0 in early 2013 to 9.8 in early 2016 — a thirty-five percent increase in three years. The Reserve Bank introduced loan-to-value restrictions in October 2013 and tightened them twice more by 2016. The Government tried a foreign-buyer registration scheme, a bright-line capital-gains test, and a tightening of investor lending rules through the LVR regime. None of it slowed the city down.

The drivers were specific to Auckland. Net migration peaked at 72,000 a year in 2016, of which roughly two-thirds settled in Auckland. Building consents lagged for most of the decade — the city consented an average of 7,500 new dwellings a year between 2008 and 2013 against population growth that needed about 12,000. The Unitary Plan, which was meant to enable significant intensification, only became operative in late 2016. Construction costs, which had been roughly flat through the 2000s, started rising at twice the rate of general inflation.

The spread north and south, 2017 to 2019

Between 2017 and 2019 the surge that had been concentrated in Auckland spread out across the rest of the country. Wellington’s median multiple climbed from 5.4 to 6.8; Hamilton from 7.3 to 7.4; Tauranga from 9.3 to 9.6; Christchurch from 5.7 to 6.0. The regions started to move too: Whanganui from 3.9 to 5.2, Gisborne from 4.4 to 6.1, Invercargill from 3.0 to 3.8. By 2019 there was nowhere in the country, except small parts of the eastern South Island, where the median home cost less than four years of household income.

The classic explanation for the spread is “ripple effect” — Aucklanders priced out of Auckland buying in Tauranga, Tauranga locals priced out moving to Whakatāne, and so on down the chain. There is some truth in that. The bigger driver was probably more general: very low interest rates by historical standards, increasing investor concentration in lower-priced markets, and a population that had spent fifteen years getting used to the idea that the house was the investment.

The lockdown spike, 2020 to 2022

The 2020–2022 spike was the most dramatic single move in the data series. The Reserve Bank cut the OCR to 0.25% in March 2020 and signalled it would stay there for at least a year. Mortgage rates fell below 3% — the lowest level since the 1960s. Net migration turned negative for the only time on record. None of that should have caused house prices to rise. They rose anyway, by 27% nationally between June 2020 and November 2021.

The national median multiple hit 8.7 in early 2022. Auckland’s hit 10.5. Queenstown’s reached 12.4, meaning a household earning the median local income would have needed twelve years of every dollar they ever earned, before tax and food and clothes and any other expense at all, to buy a median home in town. That is roughly the affordability ratio of central London at the time, in a town that has neither London’s wages nor London’s transport links.

The correction, 2022 to 2024

The market turned in early 2022. The Reserve Bank started lifting the OCR in October 2021 and pushed it from 0.25% to 5.5% by May 2023 — the steepest tightening cycle in the Bank’s history. Two-year fixed mortgage rates climbed from 2.5% to nearly 7%. House prices fell. They fell furthest in the places that had risen furthest: Wellington off 25% from peak, Auckland off about 22%, Queenstown off 20%. The smaller centres held up better, partly because they had risen less and partly because their median home was already at a level that lower-income households could borrow against.

Affordability improved as a result, but only because prices fell. Household incomes barely moved in real terms over the same period — wages were rising at roughly the rate of inflation. By the end of 2024 the national median multiple was back around 7.0, Auckland was at 8.5, Queenstown still at 10.6. Better than 2022 but very much not what 2001 looked like.

Where this leaves the buyer

The version of the housing market that exists now is not unusual by international standards — eight, nine, ten times income is the price-to-income ratio of most major Western cities. It is unusual by New Zealand’s own historical standards. The country built its post-war identity around widespread owner-occupation, and the underlying arithmetic of that identity assumed a price-to-income ratio in roughly the three-to-five range that the data series starts at. A household trying to buy a first home in 2026 is trying to do something the housing market is no longer priced to permit.

The deposit-affordability index, which the same dataset publishes alongside the median multiple, makes the same point in a different way. The deposit needed to buy a median Auckland home in 2001 was roughly $50,000 in nominal terms, which at the median household saving rate took something like four years to put together. The deposit needed in 2026 is around $190,000, which on the same saving rate takes closer to fifteen years to assemble. The mortgage itself, once you have the deposit, is more affordable than at the 2007 peak only because rates are lower, not because the underlying loan is smaller.

None of this is news to anyone trying to buy a house, which is the point. The data series here exists to make the size of the shift visible — to put a number on what most New Zealanders under forty have spent the past decade understanding intuitively. The median home, in the median city, takes roughly twice as many years of household income to buy now as it did when the data started.

Where the cheap places are

There are still pockets of the country where the math works. Invercargill at 5.8 times income, Palmerston North at 6.8, Whanganui at 7.6, Hastings at 7.4 — these are the lower-cost end of the 18 cities tracked here. None of them are quite affordable on the Demographia three-times-income test, but all of them are within reach of a two-income household earning two median wages. Below the city level, the cheap places get cheaper still: the smaller South Island districts (Buller, Grey, Wairoa) and the eastern hill-country districts (Ruapehu, Wairoa, Tararua) have median multiples in the four-to-five range and median prices under $400,000.

The trade-off, of course, is jobs. The places where housing is still affordable are places where the local economy is small, narrow, and not growing especially fast. Buying cheaply in Wairoa works if you can earn there, or work remotely, or accept the income hit. For an Auckland-based professional household, the cheap-housing places have stayed cheap partly because moving to them costs roughly the savings on the house.
