Given the popular focus on Asian migrants, as opposed to all migrants, it would appear that some of the criticism is racist. There are also other reasons for house price inflation. Despite this, some of the issues raised are valid.
There is a related issue that also often features in the media. This is the case of the so called “astronaut” families, where the wife and children live in New Zealand, enjoying the benefits of New Zealand’s education and health care system, while the husband works overseas. The breadwinner usually only visits New Zealand for short periods of time.
Anecdotally, the evidence is that most breadwinners in this situation do not pay New Zealand tax. We believe that in many cases New Zealand income tax is actually payable. This is because an overseas based breadwinner with a family based in New Zealand would probably be deemed to have a permanent place of abode in New Zealand (regardless of how little time they actually spend in the country) and they would therefore be liable to pay New Zealand tax. If enforcement and compliance was better this would satisfy some of the critics of the government’s migration and housing policies, as well as increasing the government’s tax take. On this issue, the ball is in the government’s court.
