Pop queen Katy Perry has unveiled a new song in the weirdest way - via a disco ball installed in Auckland's Britomart precinct.
The site is one of 22 places around the world fans can have a sneaky listen to Perry's new song, which will be officially released on Friday.
Eager fans need to take their own headphones to the Nike store in Britomart and plug them into the disco ball to hear the song.
The premiere only lasts until the disco ball's battery runs out. Those taking part were asked to post their comments using the hashtag, #chained to the rhythm.
