However, police still want to confirm Hyland's movements yesterday morning.
Leitch said they are particularly interested in sightings of her in the vicinity of Matai, Rata and Belvedere Rds, and Hataitai Beach between 5.30am and 6.50am.
She was Caucasian, 165cm tall and wearing black-coloured pants, a black knitted top and pink-soled running shoes.
Earlier, police said a post-mortem would be carried out today, and extended their sympathies to Hyland's family and friends.
The coroner will release their findings in due course.
