Labour says the Government is abusing Parliamentary process by nominating Associate Local Government Minister John Carter to chair a select committee on Auckland governance.
Mr Carter and four other National Party MPs will be on the 11-member committee, to consider Auckland's transition to a super city.
Mr Carter is likely to be elected chair, with the support of the ACT Party.
He says he is right for the job, but Labour's shadow leader of the House, Darren Hughes, says it is highly unusual for a minister to chair a select committee.
Mr Carter says he's only one voice on the select committee and there will be no abuse of process.
Government consultation meetings with various communities about the super-city, began in Rodney District on Sunday.
Another was held in West Auckland on Wednesday night. Ratepayers said they feared a loss of identity.
But Social Development Minister and Waitakere MP Paula Bennett says the Government will never be able to please everybody and there is a lot of misinformation about the meetings.
