Every year Coastguard New Zealand volunteers answer more than 300,000 calls.
The marine search and rescue organisation operates with the help of 1800 trained volunteers and 18,000 supporter members.
And all without any Government funding.
Next week, attention will be drawn to these unsung heroes of the sea, with therelease of Andrew Davis' film The Guardian.
Starring Oscar-winner Kevin Costner and That 70s Show star Ashton Kutcher, The Guardian looks at the lives of two American Coastguard workers, who brave high seas and past heartache to save the lives of others.
But Coastguard NZ marketing manager Daniel Birch says unlike the US Coastguard - which is similar to an armed service and fully Government funded - the New Zealand organisation is completely volunteer-driven.
In a bid to raise awareness of the cause, Coastguard NZ has joined forces with Buena Vista International and will screen exclusive advanced premieres of the film on Tuesday night.
Entry will be just $2 plus a donation to the local Coastguard unit, and will take place at cinemas across the country from 6pm.
"The idea to be involved in the premiere was about public awareness. To say, 'look, there is a Coastguard in New Zealand as well and we need public support'," said Birch.
Birch said only ten per cent of the boating public were supporting members of Coastguard NZ.
"I think there is a public perception that we're government funded so 'why should we be paying for these guys to come and help us?'
"But really we're just a club of people who've got together and said 'we need to look after each other'."
