The Old4New initiative, with the tagline 'Wear a lifejacket - It never ruined a day on the water,' was launched in November, the hundreds of jackets that have been handed in including some that had racked up half a century, from classic sailing and cork models to others that children had grown out of or had been sitting unused in the front of the boat for years.
Meanwhile Mr Gemmell said the newly-formed Coastguard unit at Houhora would be taking delivery of a 5.5-metre Coastguard rescue boat. It would be of a size that would be particularly valuable for work in harbours and inshore waters, but long-term the unit would be looking at acquiring a larger vessel, of 10 or 11 metres.
It would also be raising funds for a Coastguard building at Pukenui's Monkey Point, in the vicinity of the Houhora Big Game and Sports Fishing Club premises and the country's northernmost St John station.
"Things are going well," he added.
"We're getting more volunteer crew members all the time, although there will always be room for more."
The unit would provide a valuable emergency service in the Far North, he said, although education would also be an important part of its role.
