Stewart, who started surfing when he moved to Waihi Beach when he was about 10, says as the No 1 seed in his division, he'll be "pretty keen to take that trophy", held by Butler, who was won last year while representing Ngati Ranginui.
On top of the immense talent within New Zealand's top surfers, the Aotearoa Maori Titles offer up an opportunity for Maori surfers to take part in a relaxed event, meet other surfers from around our coastline and connect with the Maori community – an aspect of the event that is equal if not more important than the titles themselves.
Stewart says he always tries to attend the Maori nationals when he's not surfing internationally because it's a good casual competition where he can also catch up with friends.
"I always love getting down here," Stewart says.
However, although it's not an international competition, 23-year-old Stewart says his mind never strays from the task at hand no matter what the level of competition is.
"It's more casual but i still definitely keep competitive no matter what.
"I kind of get in the same headspace."
No matter what though, Stewart says he'll enjoy himself and is looking forward to the event.
Meanwhile, it is set to be a stunning weekend as a high pressure system pushes over New Zealand bringing unseasonably warm temperatures. A good pulse for swell is forecast to march up the West Coast from under New Zealand.
