Ousted New Zealand First list MP Mark Patterson said his party's "adversarial" approach to electioneering during recent weeks may have cost it a place in Parliament.
The party led by Winston Peters crashed out of power on Saturday night, after its share of the party vote plunged from 7.2 per cent in 2017 to less than 3 per cent, failing to meet the 5 per cent threshold for its list MPs to enter Parliament.
Referring to Labour's landslide victory, Patterson said the election had been won by a "red tide", which coalition partner for the past three years NZ First had failed to leverage.
"The prime minister did a great job in steering the country through [the Covid-19 crisis], and we didn't quite try and stick on the coat tails of that."
"Maybe we got a bit adversarial."
