"His family were an example of how to start with nothing and how to then commit to the reo journey. He only ever spoke te reo Māori to his children. His kids have both said they've never had an English conversation with their father ever.

In recent years Waho blew the whistle on claims of financial misspending by the Kōhanga Reo National Trust in 2013.
He lost his job after speaking out about the allegations, and the High Court later ruled his dismissal by the trust was unlawful.
Wilson said Waho always remained staunch in his views.
"He was extremely sharp and even if he had a different view he would stick to his view even if it wasn't popular. He was very determined," he said.
"Toni was also full of life, he was flamboyant and he loved to be the centre of the party.
"His reo will carry on, and that's something he has left for all of us."
Waho leaves behind three siblings, two children and three mokopuna.
