The challenge Winston Peters now has in victory is walking the walk he has talked on the hustings.
Peters has claimed a majority of 4012 votes - six months ago Mike Sabin took the seat with a 9000 majority.
It is the first time in more than 50 years National has lost the Northland seat.
Mr Peters had 15,359 to National candidate Mark Osborne's 11,347. Labour's Willow-Jean Prime had 1315. Ms Prime's vote was hit by strategic voting as Labour supporters turned to Mr Peters.
He was gracious towards Mr Osborne, who would probably have been a successful candidate if say he, rather than Mr Sabin, contested the seat in 2014.
