"I loved him and may he rest in peace."
A death notice published in the Chronicle said Karatau, known as Nate, was surrounded by his family at the time of his death. His children are aged 14, 13, 6, 3 and 18 months.
The notice said he was loved by "all his siblings, their families, and he was a cherished son to his parents".
His funeral is tomorrow in Marton.
King will be unable to attend the ceremony.
Alisha Samuel, sister of Karatau's partner, Nadine, has set up a Givealittle page to help raise funds for the family.
All proceeds will help cover funeral costs and amenities.
