She said the social media attention was partly thanks to the wider issues that the documentary addressed such as "how we move forward as a bi-cultural nation".
"Now is a time of real nation-building I think.
"And I think that this is a film that has found the right time."
Since the trailer of the film was posted on Facebook by Regent 3 Cinema at the end of last month it has accumulated 118,000 views, and has attracted large interest from within New Zealand and Australia with more than 9000 likes, comments, and shares.
The film's official Facebook page's trailer has less than one third of the attention at 34,000 views.
Because of the social media success, Wairarapa residents have been urged by Regent 3 Cinema to secure their tickets for Saturday's screening of the film at 1.15pm by booking.
Regent 3 Cinema social media manager Theus Goodwin said the video went viral because it "struck a chord with the Maori community that a lot of us didn't appreciate".
He said it was the result of targeting Facebook users with an interest in history and Maori culture who are based within 50km of Masterton.
"The event took off organically from that after being shared among people's friends and family," he said.
"But looking at the people [in the analytics], they are spread out all over New Zealand and Australia.
"We've not had a reaction like this to a movie before.
"I phoned the director and told her how it looks like it will be a sell out and we might have to get it back for a second run.
"She is really excited, and has said she might be able to return for a special appearance and korero with our audience, if we do bring it back to Masterton."
