New Zealand First will not stand a candidate in the Northcote byelection.
Leader Winston Peters this afternoon said the decision was made after discussions with the caucus and the party.
"The consensus view of New Zealand First is that standing a candidate endorses a former National Member of Parliament, Jonathan Coleman, walking out on his electorate and needlessly costing the taxpayers a million dollars," he said.
Coleman quit politics last month to run private health company Acurity.
"A National MP's thwarted ambition provides the worst possible reason to abandon an electorate," Peters said.
