Winston Peters did not hold back in his description of Simon Bridges' interview with Chinese state media, mocking it as "subservient grovelling".

Peters, the Deputy Prime Minister, used his speech in Parliament on Wednesday to criticise the interview Bridges gave Chinese state media during his visit to the superpower earlier this month.

"I have never heard such obsequious, subservient grovelling, kowtowing, palm-kissing nonsense," Peters, also New Zealand First leader, said.

He is the latest MP to attack the interview, after Finance Minister Grant Robertson described it last week as the "most extraordinary interview I think I've ever seen the leader of a National Party give".

The National leader's interview with state-owned news channel CGTN made world news, with The Guardian highlighting how it had been described as "alarming".

Bridges praised the Communist Party of China (CCP) for taking the country from mass poverty to economic prosperity in the state media interview, calling it an "amazing story".
