This year the awards final will be held online and the ceremony will be streamed on Baycourt Community & Arts Centre's Facebook page from 6pm on November 11.
Sainsbury said he enjoyed being a judge and encouraged Kiwis with a passion for filmmaking to get involved in the festival.
"Filmmaking is the best thing in the world, so if you're keen, take every opportunity to do it.
"I've loved being this year's judge. I always love seeing people's creative expression and there was something so exciting about seeing these young guys getting out there and making something."
Baycourt Manager Reena Snook said while they would have liked to host a physical awards ceremony, moving online safeguarded the festival against future alert level changes. It is the second year it has been held online.
The prizes for the winners include $1500 for first, $1000 for second and $500 for third. The top two films will represent New Zealand at the festival's global awards in the United States this year.
Other awards up for grabs include awards for directing, acting, editing, cinematography, production design and more.
To watch the final, go to the Baycourt Community & Arts Centre Facebook page on November 11.
