The Black Seeds have postponed their Christchurch show scheduled for Saturday.
The decision to postpone was the band's only option, with the state of emergency extension in place for another seven days in the central CBD following Saturday's 7.1 quake.
With no guarantees of reliable power and water, plus the threat of further aftershocks, the band said it was unwise to go ahead.
A new date of October 30 has been set and will take place at the same venue -- The Bedford -- which has not been affected by the quakes and is structurally sound.
All tickets will be transferable to the new date, or anyone wanting a refund can contact the ticketing outlets.
Black Seeds frontman Barnaby Weir said the band's thoughts went out to the people of Canterbury.
``Our sincere apologies for having to postpone, but we're looking forward to coming back in October and playing for the people of Christchurch,'' he said.
All other shows on the band's South Island tour scheduled for this week in Dunedin, Queenstown and Timaru are still going ahead as planned.
Tickets for the new Christchurch show on October 30 will go on sale from Saturday.
