The addition of the shows to Lorde's schedule raises concerns about her hectic lifestyle, especially when the first date of her rescheduled Australian tour in Perth in July was reportedly cut short because of illness. But Lorde said she was recovered and ready to hit the road again.
"I'm so great right now. It's pretty crazy when you leave your home country for the first time. My system was like, 'Hey, brand new diseases', so I got really sick a bunch of times. But I feel good, I feel okay, and very healthy ... fingers crossed."
She's taken up yoga to help sustain her touring lifestyle - and to battle nerves. "I still get crazy nervous - it doesn't go away. But I do yoga now and I stretch before the show and I do all sorts of calming things."
Lorde, real name Ella Yelich-O'Conner, has performed only four times in New Zealand: two small shows in Auckland and Wellington that kicked off her performing career last year, a free iHeartRadio show at Auckland's Vector Arena, and a Laneway gig at Silo Park in January.
But after a year that's included two Grammy Awards, a Brit award and appearances at festivals such as Lollapalooza and Coachella, Lorde said Kiwi fans could expect to see a more confident performer. "I think about those shows and I was too scared to even move. Now I'm thrashing around, doing these insane, very physical dance moves."
On Monday (NZ time) Lorde will go up against Beyonce and Katy Perry at the MTV Video Music Awards, where she is nominated for Best Female Video and Best Rock Video.
