Palmerston North City Council has postponed the New Zealand Tattoo, which was to be held in the city on April 12 and 13.
Council chief executive, Heather Shotter, said the decision to postpone the event was carefully considered.
"While the tattoo was to feature a large number of New Zealand's top pipe and brass bands and kapa haka, a significant part of the event was to feature military displays that included firearms and explosives," Shotter said.
"Following the recent events in Christchurch, the council considers it would be inappropriate to host an event of this nature.
