Former Prime Minister John Key and Labour MP David Cunliffe have struck a deal so they can both leave Parliament early.
The announcement means a by-election wont be needed as they are leaving close enough to the general election.
John Key last week he would give his final speech to Parliament next week before his resignation as an MP took effect on 14 April.
Mr Key has not announce what he plans to do when he leaves Parliament.
Mr Cunliffe, who led Labour at the 2014 election, would also leave in April to take up a job with a management consultancy firm.
Acting Prime Minister Paula Bennett said the deal for Mr Key and Mr Cunliffe to leave at about the same time was a decision agreed between themselves.
