Northland's new National candidate is Doubtless Bay business owner and council employee Mark Osborne from Taipa.
Voting at Saturday's selection meeting had to go to a fourth round before Mr Osborne had an absolute majority of ballots cast by the party's 118 Northland delegates.
Four other nominees made it to the final shortlist - Mita Harris, Matt King, Grant McCallum and Karen Rolleston - with the delegates' final choice a tight three-way race.
The Advocate understands the final ballot was between Mr Osborne and Mr McCallum, a Maungaturoto dairy farmer. Matt King, an Okaihau farmer and fraud investigator, was eliminated one round earlier.
About 150 people attended the selection meeting at Kerikeri Sports Complex.
Mr Osborne wasted no time after his selection, immediately taking leave from his job as Far North District Council asset manager and an hour later hitting the campaign trail at Kerikeri's Ocean and Orchard Festival.
Mr Osborne said he was very pleased to have won the delegates' confidence and paid tribute to the other nominees. All were staunch National people with bright futures in the party, he said.
