China has barred four New Zealand politicians from entering the mainland, Hong Kong and Macau for a year after they visited Taiwan in May, NZ media reports.
The New Zealand Herald newspaper on Thursday said the Chinese embassy notified parliament that Laura McClure, David Wilson and Maureen Pugh, from parties in the ruling centre-right coalition, and opposition Labour lawmaker Duncan Webb were subject to the ban.
The Chinese embassy told NZ parliament officials the travel ban could be reduced or waived if the politicians apologised for the trip, the Herald reported.
A spokesperson for Foreign Minister Winston Peters said New Zealand politicians had visited the democratically governed island for decades.
"Such visits are not inconsistent with New Zealand's One China policy," the spokesperson said, referring to its policy since 1972 of recognising Beijing as the sole government of China.
"In the context of that long history, the minister was surprised to learn that China has taken a decision to, for the first time, impose travel bans on New Zealand MPs as a result of travel to Taiwan."
Peters instructed NZ foreign ministry officials in Beijing and Wellington to discuss the matter with Chinese authorities "in order to express concern at this departure from past practice and to better understand it".
New Zealand and China have maintained a largely stable relationship in recent years, with China remaining NZ's largest trading partner, even as Wellington has grown more outspoken about Beijing's expanding influence in the Pacific.
Senior politicians from both countries have exchanged a number of visits over the past three years, with New Zealand Prime Minister Christopher Luxon visiting China in 2025.
China views Taiwan as its own territory, and has not ruled out the use of force to take control of the island. Taiwan's government rejects Beijing's sovereignty claims.
The Chinese embassy in Wellington did not immediately respond to a request for comment.
McClure told the newspaper the travel ban was "a type of foreign interference".
"I'm not going to apologise for visiting Taiwan," she said.
The Chinese embassy told NZ parliament officials the travel ban could be reduced or waived if the politicians apologised for the trip, the Herald reported.
A New Zealand parliament official confirmed a meeting with Chinese embassy representatives but did not disclose details.
"Any advice given to MPs is always on a confidential basis," David Wilson, Clerk of the House of Representatives, said by email.
Like most countries, New Zealand has no formal ties with Taiwan. Under NZ's constitution, members of parliament are independent of the government and make their own travel decisions when invited.
