Labour leader Phil Goff believes list MP Kelvin Davis should beat Hone Harawira in any election or by-election in Te Tai Tokerau.
Mr Harawira has delayed submitting his resignation to the Speaker while he consults further with staff and his electorate.
But Mr Goff says Mr Davis, a former Kaitaia Intermediate School principal, is up for the rematch.
''Kelvin (is) from the north ... and a man of the future.'' he told Waatea News.
Mr Goff said he hopes there won't be a by-election, because the new MP would have less than two dozen sitting days in Parliament before the general election.
