"With Auckland in a form of level 3 for some weeks to come, and uncertainty around when capacity limits will be lifted, it is no longer possible for us to go ahead with the Auckland edition of this year's festival.
"The team, led by director - Kaiwhakatere Marten Rabarts and general manager Sally Woodfield, has worked under extraordinary circumstances to do everything possible to present this year's festival in all 13 towns and cities, and our programme confirmed for 2021, featuring an outstanding line-up of award-winning films from around the globe, is one that we are extremely proud of."
The trust is working towards having the festival in the rest of the country under the current alert level 2 restrictions.
Fitzgerald said audience safety is paramount and the trust is working with venues to ensure this.
"We are working with venues and cinemas on the logistics of presenting under the level 2 restrictions with the removal of the cap on capacities, but with various continuing level 2 requirements including physical distancing.
The festival opens in Christchurch on October 29, Wellington on November 4, and Dunedin on November 5, followed by nine regional centres.
The full programme will be announced in the coming days.
