In Auckland, the share of houses sold to overseas residents was slightly higher than the rest of the country, at 4 per cent.
Chinese tax residents bought 372 out of 648 (57 per cent) of the Auckland homes sold to overseas residents in the last three months.
The proportion of New Zealand houses being bought by people living offshore between July and September was similar to the previous two quarters.
In all, 60 per cent of house sales and purchases in the last quarter involved people who had only New Zealand tax residency.
Another 37 per cent involved people who did not need to provide tax information - mostly New Zealand citizens or residents buying their main home.
The data also showed that overseas residents were responsible for 3 per cent of the house sales in New Zealand.
