The Coroner in an inquest into the 2004 disappearance of Iraena Asher is due to present his findings today.
The week-long inquest at the Auckland District Court has heard emotional evidence from Ms Asher's family and friends, as well as the police theory that the bi-polar sufferer had a manic episode that resulted in her drowning in the Piha surf.
Yesterday, one of the people who was with her on the day she disappeared revealed she had taken hard drugs that day,
Henry Woodhouse told Coroner Peter Ryan of disjointed and bizarre conversations he had with Ms Asher in the hours she spent with him at his mother Julia's Piha home.
Mr Woodhouse and his mother picked up Ms Asher and took her to the house after finding her walking along the road in the rain wearing little more than underwear.
Ms Asher told Mr Woodhouse varying stories over the night about how she had been given acid and ecstasy.
Mr Woodhouse helped his mother and her partner Bobbie Carroll comfort Ms Asher, and reassured her she was safe.
Later that night she left the house, ignoring Mr Woodhouse's attempts to stop her.
The last person to see Ms Asher alive also gave evidence yesterday.
Zachary Nixon told Coroner Ryan he was restless, so decided to walk his dog at about 1am. He was with his then-partner Simone Ross.
The couple saw Ms Asher standing naked under a street light. The pair followed her for a while, but lost her near the beach.
Mr Nixon told the inquest he did not think to call 111 after seeing the naked woman because "she didn't seem distressed".
Ms Ross said people swimming naked at Piha was a common occurrence and so seeing Ms Asher in that state "wasn't really a surprise".
The Coroner also heard evidence from Ms Asher's father Michael and older sister Angelique Campbell.
Mr Asher spoke of her history of mental illness and his efforts to keep her safe when she was having a bipolar episode.
Mr Asher said his daughter's death had a major impact on the family, and nothing would change that.
"Whatever we do, whatever we say here, it's not going to bring Iraena back," he said. "So what's the point?"
Mrs Campbell gave evidence next, describing Ms Asher as bubbly and outgoing. She was adamant her sister was not depressed and was "religious" about taking care of herself as she hated when she was affected by her disorder.
