An ageing population is playing into an increase in urban Land Search and Rescue missions.
Over the past six months, the volunteer group's been called on 23% more year-on-year.
It's meant 22% more volunteer responders have been deployed.
Chief development and project officer, Johnny Franklin told Andrew Dickens that alongside alpine and bush rescues, urban rescues have been of particular concern.
He says urban rescues account for about 25% of operations and is expected to increase as the population gets older.
