New Zealand PM Jacinda Ardern wins second term in landslide election victory

Jacinda Ardern has won a second term as New Zealand's Prime Minister after her success at handling the country's coronavirus outbreak helped secure a landslide victory.

With 77% of the votes counted, Ardern's center-left Labour Party has won 49% of the vote, meaning her party looks likely to score the highest result that any party has achieved since the current political system was introduced in 1996.

Coalitions are the norm in New Zealand, where no single party has ever won a majority of votes under the current system.

Labour's main opposition, the center-right National Party, is on 27% -- down on last election's 44% and likely to be the party's worst result since 2002.

National leader Judith Collins said she called Ardern to concede defeat and congratulate Ardern on an "outstanding result" for the Labour Party.

Results are still being counted. Final results will be released in three weeks once special votes -- including those cast by New Zealanders living overseas -- are counted.
