Epsom MP John Banks is being chastised for showing too much bravado.
Police are investigating donations received by the ACT leader when he ran for the mayoralty of Auckland in 2010.
The donations reportedly included $50,000 from Megaupload founder, Kim Dotcom, but were declared as anonymous.
Mr Banks insists he has acted within the law.
But his former colleague and rival, Christine Fletcher, who is now the councillor for much of his Epsom electorate, says she does not believe he will or should resign, but he should not be quite so cavalier.
Mrs Fletcher says the people of Epsom are very fair minded but want sincerity.
