New Zealand First leader Winston Peters is vowing to continue pursuing Justice Minister Judith Collins over her trip to China, and says he has more information to come.
Ms Collins has been on stress leave for a week, after facing months of attacks over her dealings with export company Oravida, of which husband David Wong-Tung is a director.
Mr Peters on Tuesday said Ms Collins had failed to disclose travel and accommodation provided by the Chinese Government during her trip there last year.
On Wednesday he said he would have thought that information would have been enough to cause the Prime Minister to finally act.
"I assumed that we had a standard of accountability from the prime minister. Clearly there are no standards," Mr Peters said.
"She told seven direct statements that were not true.
"I add the eighth one and you say 'so what else have you got'? Well I have got more, and it'll be coming, and I'm in no great hurry to ease their angst and concern about this campaign."
Prime Minister John Key on Tuesday said that, at worst, Ms Collins would have to amend her declaration to the Registrar of Pecuniary Interests.
