"The fact this is open to any New Zealander is great and I'm very excited for people who enter.
"Being able to throw a net out really wide and catch new talent, particularly young, raw talent, is great.
"It is imperative that we have bodies that keep supporting the arts and culture. If our creative voice dies off it amputates a massive part of our community."
Cormack shared some of her winning tips with the Herald on Sunday: the pilot must be authentic and have the ongoing potential to make a full series.
"Even if it is absurd, as long as you are telling a story you really want to tell, it will resonate," she said.
"Don't feel like you have to pull out an Oscar-winning masterpiece as your pilot."
The main criterion is that entries must be relevant to New Zealand.
Actor and filmmaker Millen Baird, TV critic Alex Casey, YouTube star Adam King and Three Wise Cousins director Stallone Vaiaoga-Ioasa are also part of the 11-strong panel.
TVNZ's digital creative director Amie Mills was excited to see the range of ideas Kiwis would put forward.
"We're thrilled with the panellists. The breadth and brainpower of their combined experience will ensure the shortlist features local content unlike anything else on offer.
"We wanted to create a competition where people can put an idea forward that might be really left field or different, as a way of supporting local content and creating greater opportunity for new voices."
Mills said airing the series online provided the opportunity for niche content that might not appeal to a wider television audience, to be seen and heard.
The winner's series will be launched on TVNZ OnDemand.
