"Police had a rescue team go out and search for her and her car was recovered from the Tolaga Bay wharf car park.
"She'd had mental health issues for a couple of years, but they were under control. But because of those police were convinced she committed suicide."
Oli-Alainu'uese believes police should have further investigated whether foul play was possible.
"I was the last phone call she ever made, but I could see from phone records that her phone had been used after she 'committed suicide'."

Gisborne police Detective Sergeant Daniel Kirk said throughout their investigation into Jamie's disappearance they had spoken to her relatives and close friends to establish her movements.
"While police understand her family and friends' significant frustration with all the unanswered questions regarding her disappearance.
"Unfortunately some of the information that's being circulated is inconsistent with the facts gathered through our investigation," Kirk said.
He said the investigation was been handled by the Criminal Investigation Branch and was being reviewed by a senior investigator.
Oli-Alainu'uese's family has gathered and searched for Jamie every day this past week.
"We have searched the best we can, and have covered huge areas but there is still so much to go.
"About 10 of us went searching for her when she went missing but that number is gradually growing."
She said she understood they might never find Jamie, but they remain hopeful.
"My only outcome is we lay her to rest. We are not expecting to find her alive, but we have to stay hopeful.
"My only objective is to find her, and I will go out over the next couple of days with family to search for her."
