Police are renewing calls for the public's help in their investigation into the disappearance of Waikato woman Kim Richmond more than five months ago.

The 42-year-old was last seen during the early hours of July 31, 2016, when she left her Wharepapa South farm near Te Awamutu in a silver 2014 Ford Ranger utility.

Detective Paul Galletta describes Kim as wearing a Highlanders rugby jersey, blue jeans, brown leather jacket and brown leather boots at the time of her disappearance.

'Unfortunately it has been a long time since Kim went missing and we believe it is unlikely that she will still be found alive.

'The investigation into her disappearance, which is completely out of character, is very much still an active one and we're focused on finding her and establishing the circumstances around what has happened.

Paul says finding Kim's vehicle is of utmost importance to police and is asking people to keep an eye out for a Silver 2014 Ford Ranger utility with the registration number HKD553.

'We also want to hear from you if you think you may have seen Kim any time after July 31st 2016.”

Police are also still seeking Kim's silver 2014 Ford Ranger utility, registration HKD553.

Police also want to hear from people who may have seen someone throwing items out of a vehicle on State Highway 46 in late September or early October.

Around that time, two bank cards and a farm card belonging to Kim were found on the roadside between Rangipo and SH47 near Otukou, explains Paul.

'Subsequent checks in the area carried out at the time by Police Specialist Search Teams discovered nothing further but somebody may have seen something which could point us in the right direction.

'This has been a trying five months for Kim's family and friends and we thank them for their support in our investigation.

'If you think you may have even the smallest piece of information about Kim or the vehicle which may help us in our investigation, please come forward.

If you have seen or have any information relating to Kim's 2014 Ford Ranger utility, registration number HKD553, or her whereabouts please contact Te Awamutu Police immediately on 07 872 0100.
