The councillor caught out on a junket to the Gold Coast declared the trip to officials - but concedes he may have done so after a call from a journalist.
But Cameron Brewer said his declaration wasn't prompted by a call from Herald media specialist John Drinnan. Instead, he said it was a council official's email that raised concerns about his free flights and accommodation.
Mr Brewer's stand against Auckland Mayor Len Brown was brought up short when he was exposed as not having declared the August 2011 trip to Australia.
On Sunday, Mr Brewer revealed he had actually declared the trip but only for the council's gifts register and not the Register of Members' Interests.
