Prime Minister John Key and Foreign Minister Murray McCully are weighing in behind Trade Minister Tim Groser at speculation he may have breached cabinet rules by criticising the change proposals at the Ministry of Foreign Affairs and Trade and that he had been interviewed by the inquiry into leaks.
Speaking to reporters in the Cook Islands where they are at the Pacific Islands Forum, Mr McCully said he could hardly blame any minister for criticising the proposals when he, himself, had issued four pages of criticisms.
And Mr Key said that he would have expected Mr Groser to be spoken to by people to be undertaking the inquiry into leaks.
"It is not at all unusual for minister to be spoken to when these reports are done otherwise they wouldn't be done with integrity and in that regard, of course Tim would be a person who would be spoken to."
Mr Key himself had been spoken to by the office of the Auditor-General when it was conducting an inquiry into the national convention centre tender.
