Labour leader David Shearer is being accused of hypocrisy after accepting an MP at his word over a potential immigration scandal while demanding a higher standard from Prime Minister John Key.
Mr Shearer says he sought and received assurances from Labour MP Shane Jones that he followed proper process when granting citizenship to a fraud-accused Chinese millionaire as associate immigration minister in 2008.
Yong Ming Yan, also known as Bill Liu, is on trial in the High Court at Auckland on four charges of using false declarations on immigration papers in 2001 and 2002, and one charge of using false written statements to get citizenship.
The court last week heard that Yan boasted to immigration officials that his connections with MPs would ensure he got New Zealand citizenship, and that he was going to take the MPs to China.
His application was rubber-stamped by Mr Jones, despite advice from Department of Internal Affairs officials that he did not meet the good character test.
Yan was also red-flagged by Interpol.
In a statement on Monday, Mr Shearer said he had looked at the information Mr Jones had about the application, and it appeared the process was "considered and proper", and Mr Jones felt immigration officials had not established a clear case against Yan.
Mr Shearer previously demanded Mr Key stand down his ministers Nick Smith and John Banks while their conduct was investigated, instead of taking them at their word - and Mr Key says now the tables have turned, Mr Shearer is a hypocrite.
"He talks tough, but the first situation ... he's simply taken the guy at his word," Mr Key said.
"I'm not questioning Shane Jones' word, I was always very cautious as leader of the opposition before I leapt in and criticised others, and David Shearer hasn't been."
