Figures from Juwai.com - a top Chinese international property website - show New Zealand has dropped down to the sixth most popular country in the world for Chinese buyers after being in fifth place for the past two years.
China's interest in buying New Zealand property was already on the wane ahead of a new clampdown on foreign buyers.
Jane Lu, head of Australia and New Zealand for Juwai.com, said the change had been driven by a capital clampdown in China and a shift by buyers to purchase lower-priced international property.
"We believe this change is primarily due to changes in the Chinese regulatory landscape such as capital controls, as Chinese buyers play it safe and purchase lower-priced international property.
"So, New Zealand dropped one place in the global country ranking, while Thailand catapulted three places upwards, from sixth to third."
The changes come ahead of plans by the new Labour-led government to clamp down on foreign buyers.
Under its agreement with New Zealand First it will ban foreigners from buying existing homes.
Lu said any new restrictions could cause buyers to bring forward purchases they were planning to make in the next year.
"We saw the same thing happen in Vancouver, Melbourne and Sydney when new taxes and restrictions were introduced.
"One premium buyer in Sydney closed his transaction 15 minutes to midnight before the new regime kicked in."
Auckland remains the most popular city for Chinese buyers followed by Christchurch, Wellington, Queenstown and Hamilton.
Lu said three-quarters of Juwai.com's buyers in New Zealand said they were looking for property for their own use, either as a first or second home.
"About one fifth are purchasing a home for a family member to live in while studying in New Zealand."
