Lorde dominated the Vodafone New Zealand Music Awards with a clean sweep, winning six prizes, including best album, best single and the publicly voted People's Choice Award.
The 21-year-old began the night on a high, winning the first award of the night for best solo artist, before returning to the stage to collect best pop artist.
She also claimed the International Achievement Award for the fourth time, before taking to the stage for a stunning live performance of her hit single Green Light.
The end of the night saw her claim a total of six awards, bringing her lifetime haul of New Zealand Music Awards to 18.
Accepting the award for Album of the Year, the Kiwi star brought her brother on stage to celebrate.
"This one is so important ... I put everything I had into this record, I gave it everything, I wasn't sure what the path was ... I think it's going to be one of the most important things I make."
Earlier, Prime Minister Jacinda Ardern presented Lorde with the People's Choice award.
"I'm surprised I can be people's choice after all these years of harassing you," Lorde joked to a packed Spark Arena.
Onehunga rap crew SWIDT also had cause to celebrate, named best hip hop artist and claiming the best group title, while last year's breakthrough winner Kings was recognised for having the year's highest selling single and won the Radio Airplay Award for his single Don't Worry 'Bout It.
Hamilton rockers Devilskin were named the year's best rock artist, while indie darling Aldous Harding won best breakthrough act and best alternative artist. Harding was unable to claim her first VNZMA win in person as she was playing a soldout gig in Brussels.
The night's highlights included live performances by Teeks, Devilskin and Stellar*, who reformed to play a special tribute version of Maxine, honouring this year's Legacy Award recipient Sharon O'Neill.
