Migration matters for house prices

Susan GuthrieEconomics

They say a picture can paint a thousand words – so let’s save words and cut straight to the chase on the issue of immigration and house prices…


housing and migration


Over the past two decades migration has had a strong influence on New Zealand’s property prices. Net long term inward migration is the number of people arriving who intend to stay minus the number of people leaving who intend to stay away. When the net number has been positive and large, house price inflation is high. When the number is negative or low house price  inflation is negative or low too.

Net inward migration has been rising over the past two years and this hasn’t yet had the boost effect on house prices you might expect.  It seems likely that some of this is due to the RBNZ’s loan deposit restrictions, which was designed to keep the lid on prices. The composition of migration might be another factor (some migrants may simply live with family members already resident here). The experience from 1998 to 2000 shows that the relationship between migration and house prices isn’t exact – the trends can diverge for a while. But with last week’s Budget economic update forecasting that net migration would stay above 20,000 for the next two years, it looks like upward pressure on house prices will be with us for a while.

As an aside, there’s been a lot of finger-pointing recently, as people try to blame particular groups of migrants for house price pressures. The fact of the matter is in the year ended March 2014, 13,000 more people left NZ permanently for Australia than came the other way so you can’t blame Australia’s economic woes for what’s happened in housing. The coming year may be a different story though – outflows to Australia are falling and inflows are rising. Last year the flow of New Zealand expats returning from Australia was the highest in over two decades. With over 500,000 New Zealanders living in Australia, the potential impacts are significant.

A common myth is that most of New Zealand’s migrants arrive from China. The UK has actually been the source of most migrants. The significance of migration from the UK can be summed up best with this simple fact: since 1992 101,000 people (net) have arrived from the UK to live permanently in New Zealand. Sure, some of these may well be returning Kiwi expats, but no-one knows how many. Net long term migration from China over the same period was 95,000, India 72,000. So while focusing on migration patterns from Asia seems to be a hobby for many, it won’t get you very far if you want to understand fundamental pressures in the housing market.
