The search for an Auckland woman missing in Piha since Friday will be scaled back, police say.
Kim Bambus, 21, was last seen on Friday morning, when she told friends she was going for a run.
Search teams have been focusing their efforts in the area below the Mercer Bay cliffs track and the surrounding shoreline in the past few days, but they have found no sign of her.
Police said they had also been looking into Ms Bambus' movements and activity in the weeks leading up to her disappearance, including checks of her internet and phone searches.
But they said there was no evidence to suggest there had been any foul play.
Police said they had reached the point where all possible search options had been exhausted, so the search would be scaled back.
'I don't see her going off the track'
Meanwhile, the sister-in-law of another Auckland woman who went missing near Piha said it was unlikely anyone would venture off the tracks in the area.
Cherie Vousden disappeared on the Mercer Bay loop track in 2012 - the same track that has been the focus of the search for Ms Bambus.
Ms Vousden's body has never been found, but a coroner ruled the 42-year-old mother was presumed drowned.
Her sister-in-law, Rachel Vousden, said the bush was dense, the tracks were clearly marked - and her sister-in-law would have stayed on them.
"I don't see her going off the track. It was somewhere she went regularly, she knew it inside out."
