Around 82 per cent of houses in the country are being bought by New Zealand residents or citizens, Land Information NZ says.
Another 16 per cent of sales are to businesses or corporate entities, almost all of which were wholly owned by Kiwis.
The Government department released the latest data on sales to foreign tax residents today.
For the first time, it included information about buyers and sellers' residency and citizenship status.
Until now, the statistics have been based solely on tax residency, and have consistently shown that around 3 per cent of houses were sold to offshore tax residents.
