"There is a need for this service in Wairarapa, we want to find patients before they get too distressed and lost."
"It will also give caregivers peace of mind," he said.
The chairman of the Wairarapa Community Health Trust Garry Daniell said the tracking system was an essential service for the community.
"The responsibility to look after our community is our top priority, we want to safeguard and take responsibility for our citizens," Mr Daniell said.
There is only one active pendant in Wairarapa so far but Search and Rescue Wairarapa expects there will be five autism patients and 14-15 dementia patients whose caregivers will apply for the pendants or watches in the near future.
Mr Milligan said there was a case in Auckland where a dementia patient went wandering and got stuck in a creek.
The patient was hypothermic when Search and Rescue eventually found them.
He said if the patient had been wearing a pendant the search group would have found them long before hypothermia set in.
In January elderly woman Roma Roberts wandered from Metlifecare Retirement Village in Masterton, sparking a substantial 19-hour search by rescue services and the public.
She was found hunkered down in the laundry of a neighbouring property.
Mr Milligan said the Wandatrack system takes pressure off police and Land Search and Rescue resources.
The pendants or watches cost $290, organisations applying for a pendant may be asked to make a donation towards this cost or may be eligible for a fully funded beacon.
