Tropfest, the world's largest short film festival, has announced Sam Neill will become an official ambassador for the inaugural Tropfest NZ.

The internationally renowned actor says he is excited to support the event, which is taking place on January 27 next year.

"Finally, the brilliance that is Tropfest on our very own shores. I am fizzing at the thought and thrilled to be part of it. Filmmakers of Aotearoa - start your engines!" he said.

Tropfest NZ will present its first stand-alone short film festival at the TSB Bowl of Brooklands in New Plymouth. Open to the public and free to attend, this event has been designed to encourage filmmakers from the grassroots level up.

Neill joins other Tropfest NZ ambassadors, actor Martin Henderson, director/producer/actor Katie Wolfe, actor Robyn Malcolm and director/screenwriter Vincent Ward. Other ambassadors will be announced in the coming months.

Entries are now being accepted by any Kiwi keen to participate in Tropfest NZ. Films cannot exceed seven minutes and must contain Tropfest's Signature Item (TSI), which in 2013 is "GUMBOOT". Competition details can be found at tropfest.co.nz
