The number of people in need of emergency care through Life Flight's Rescue Helicopter rose by 11 per cent last year, meaning community assistance is now more vital than ever for the charity which relies on public support.
Last year, in Wairarapa, 140 patients were flown by the Life Flight Westpac Rescue Helicopter and Air Ambulance, which is, on average, three people every week.
It costs the Wairarapa community about $2500 every time Life Flight is called out in the region.
Life Flight Trust communications and PR manager Sebastian Grodd said the increase was mostly in primary medical missions, flying very sick or injured people to Wellington Hospital for urgent medical care.
Mr Grodd said there was a "constant challenge" to raise enough money to keep the service available at all hours, with about $3.5 million needed from the New Zealand community, annually, to keep saving lives.
