A Fire and Emergency New Zealand spokesperson said the cause had been a fire in the home’s chimney which was not suspicious.
The spokesperson said it was a reminder for anyone with a fireplace to get their chimney cleaned before the first fire of the season.
It was also found the home had no smoke alarms.
“Fire and Emergency recommends working smoke alarms in every living area, hallway and bedroom,” the spokesperson said.
Men killed in fire ‘joined at the hip’
Ropitini-Fairburn had been a “loved member” of Kaihaka kapa haka group, founder and owner Eru Rarere-Wilton said.
He noted Ropitini-Fairburn travelled to other countries, including China and Italy, to perform with the group.
“Kiwa was my wife’s nephew and lived with us for a bit before moving into that house with his best friends.
“It’s all come as a shock. He was such a loving and beautiful soul and so talented.
“He had an amazing singing voice and when we were in China they all called him the karaoke king.”
Learning of the deaths of Ropitini-Fairburn and Marsters was “deeply saddening”, Rarere-Wilton said.
Kiwa Ropitini-Fairburn and Tony Marsters were “like brothers”, Rarere-Wilton said, after becoming friends at Kia Aroha College while studying coding.
They both continued their education in communications at AUT, and recently worked in hospitality, he said.
