Lorde has confirmed she won't be able to headline January's Auckland leg of the St Jerome's Laneway festival because of the Grammy Awards.
But she'll be offering a free concert to ticketholders two days later to make up for it.
The North Shore 17-year-old scored four Grammy nominations on Saturday: Record of the year, song of the year and pop solo performance for her No. 1 hit Royals and best pop vocal album for her debut Pure Heroine.
As a result, she'll need to be at the ceremony at the Staples Center in Los Angeles on January 26 - almost exactly the same time as she's due to headline Auckland's leg of the Laneway festival on January 27.
Laneway organisers said the "tight timeframe" meant she wouldn't be back in time to perform, and they fully supported Lorde's decision to skip the festival.
