This week marks the first anniversary of the disappearance of Whangamata widow Alison Philip, whose car was found abandoned at Bowentown.
Following an inquest last month, Coroner Gordon Matenga has ruled the 79-year-old died on or about August 4, 2013, "in circumstances and of causes which are unknown".
Mrs Philip was reported missing on August 8, 2013, after her silver Honda Accord was found locked but with the boot open in the Anzac Bay carpark at Bowentown.
A Bowentown resident reported seeing it parked there two days earlier.
Police said at the time Mrs Philip's disappearance was out of character, and it was unknown why she had visited the area - almost 47km from her home.
