Ms Kahukiwa said she wanted her brother's body home.
"We want him to come and be with me and his nieces and nephews in Gisborne, then we can go and visit him all the time," she said.
"It's so important to bring him home. Melbourne was his life, but it's not home. It's important for him to be back with his family, he needs to come back to his roots and be with us.
"He was so, so caring, he would always put everyone else before him. He always worried about everyone else. He loved his friends, he was loyal to them. A lot of his friends have been messaging me.
"He did a lot of living in his 20 years, he loved being around people and being with his friends, he was always on a mission.
"He was just a really neat boy. He was loved by his family and especially his friends."
Maori Party co-leader and Waiariki MP Te Ururoa Flavell said the issue of bringing bodies back to New Zealand was serious and needed to be looked at.
The Maori Affairs Select Committee is conducting an inquiry into whanau access to and management of tupapaku.
Mr Flavell said he had a similar circumstance with a family member who died in Australia just two weeks ago
"I can understand that people would be anxious about deaths that happen in Australia."
He said it could be really hard on the family when they couldn't get a body brought home, especially when costs were involved.
