Festival events included kapa haka, sport, debates, art and music.
Chair of the tribal committee overseeing the festival Matt Te Pou announced the cancellation today after consultation with iwi members.
"We assessed the public health risk to our people and made this decision to address their safety and contain Covid-19," he said.
He said it was a great disappointment as many people had been working tirelessly and voluntarily to prepare for the festival.
"I want to thank them for their commitment which has always been inspiring.
"But our decision is a critical step in Aotearoa-New Zealand's response to keep transmission rates of Covid-19 low and Tūhoe will protect its own communities by doing so."
The festival will celebrate its 50th anniversary in 2022.
