Kingmaker Winston Peters has announced his New Zealand First Party will throw its support behind the Labour party leader Jacinda Arden.
Ardern will claim the top job after only two and a-half months as Labour leader – and follows her former mentor Helen Clark into the top job.
Ardern took over as party leader from Andrew Little in August in a unanimous vote.
At 37, Ardern will be New Zealand’s third woman Prime Minister, after Jenny Shipley and Helen Clark.
She will also be New Zealand’s second youngest ever Prime Minister, after Edward Stafford who was also aged 37 when he took office 161 years ago.
The decision has just been announced at Parliament by New Zealand First leader Winston Peters.
