About 12 years ago, Poi E: The Story of Our Song star Maaka Pohatu often felt down, struggled to sleep and overanalysed the smallest of interactions.
Now the 37-year-old actor and musician, who plays Dalvanius Prime, the Kiwi legend behind the 1984 te reo hit Poi E, is doing the 22 Pushup Challenge, in part to talk about his experiences with mental illness.
The challenge stems from the global movement #22KILL which started in 2013 after it was revealed an average of 22 US veterans commit suicide a day.
Friends nominate each other to post videos on social media of themselves doing 22 push-ups a day for 22 days.
"I thought my depression was fatigue or iron deficiency and that I needed sleep therapy or iron pills," Pohatu told the Herald on Sunday.
"I was in my final year of Toi Whakaari drama school, which is a challenging environment anyway. I was trying to be happy and quiet, and positive and energetic for everyone else.
"I wanted to strive, to prove that I could reach the pinnacle of everything, but in doing so I was quite hard on myself."
Pohatu's struggle reached a crisis point while he was staying on a farm in Nuhaka, near Gisborne, for a school secondment.
"Everyone in my class went off and did something different and then the idea was to bring all our experiences into the end-of-year show.
"I ended up having a nervous breakdown in front of the guy I was staying with.
"It took a while for me to register what had happened."
Pohatu left Toi Whakaari and stayed with his mother in Marton for four months.
"I was diagnosed with bipolar disorder. The turning point for me was when I allowed myself to be ill, then I was able to start healing.
"I was lucky to have a huge amount of support from mum and the rest of my family and friends.
"Part of my healing was learning to be kind to myself. I realised I would never be as negative to my family and friends as I was to myself."
Pohatu moved back to Wellington and redid his final year of drama school. He did an assignment on the connection between mental illness and actors, and spoke about his experiences to his class.
"Depression can affect anyone but it is quite common among creatives.
"In order to create, you've got to put a lot of senses into your work and draw from a lot of places.
"Then there's also stress over finances because work is not always guaranteed, and there's a level of criticism no matter your work."
Since drama school, Pohatu has performed in multiple stage and TV productions, been in his first feature film - Robert Sarkies' black comedy Two Little Boys - and had global success with his showband-style group, the Modern Maori Quartet.
He no longer receives counselling or takes medication, but still checks in with doctors, and is wary of the occasional high as well as low.
He took his mum to last week's well-received premiere of what he describes as the "beautiful and very nostalgic", Poi E film.
