The Paramore concert at Christchurch's CBS Arena scheduled for Tuesday, January 21 has been cancelled.
A statement from Ticketek blamed the cancellation on "a change in the band's scheduling of activities which unfortunately necessitates the band departing earlier than previously planned".
The show at Vector Arena on Sunday, January 19 was not affected and "will definitely go ahead".
Fans who have bought tickets online or by phone will be fully refunded automatically to their credit card within 10 days.
Those who bought tickets through an agency should return to the agency for a full refund.
The punk-leaning American rock band's self-titled fourth album went straight to No 1 in New Zealand this year.
Its career scarcely faltered despite the 2010 departure of brothers Josh and Zac Farro. Singer Hayley Williams said the change allowed Paramore to take more risks and move outside their comfort zone.
