New Zealand is just one of three countries in the Asia-Pacific region that does not have any restrictions on foreign property ownership, according to a Knight Frank Research report.
Fears that overseas buyers could be taking advantage of low interest rates as a ticket to buy real estate in the region, pushing up prices in the process, have led to governments imposing curbs.
The report, released in mid-July before Labour's announcement that it would restrict non-resident purchases of homes if it won the next election, noted that in many countries, foreigners cannot acquire properties if they are not already residents.
New Zealand, Japan and South Korea were listed as the three countries with "no restrictions".
"Foreign ownership of property can be an emotive issue. While in Japan, South Korea and New Zealand, a foreign purchaser should have no significant issues, other countries across Asia-Pacific have a full spectrum of restrictions for both non-resident and resident foreigners," the report says.
