Australian detectives have travelled to New Zealand to reinterview witnesses about the disappearance of a Sydney nurse who was last seen 27 years ago.
New South Wales deputy state coroner Paul MacMahon is investigating the disappearance of Mary Louise Wallace, who was last seen on 24 September, 1983.
Police say the 33-year-old was seen getting into a car belonging to Robert Adams, after meeting him at the Alpine Inn Hotel at Crows Nest in Sydney's north.
The inquest has heard how Mr Adams drove the car to a nearby street to have sex with her only to wake up hours later to find her gone.
Days later he was seen washing his car seat covers and vacuuming the interior of his car boot.
Detectives travelled to Western Australia and New Zealand to reinterview witnesses ahead of the inquest.
