The partnership between Coastguard NZ and water safety equipment manufacturer Hutchwilco provides the opportunity for boaties to check and upgrade their lifejackets
Those who bring in their old, damaged or out-of-date lifejackets can get a good discount on new ones.
"Lifejackets that are over 10 years old should be replaced even if they look okay to the eye," says Coastguard chief executive Patrick Holmes.
"Seawater, sun and general wear and tear impact how effective they are and many old lifejackets won't even float which is a serious concern in an emergency."
Holmes says it is worrying that many people are also still using lifejackets filled with kapok which can absorb water.
"These are extremely dangerous so if you have one, destroy it immediately and replace it with a new, modern one.
"The Old4New Lifejacket Upgrade campaign provides an easy and accessible way for people to check their lifejacket is up to scratch, and replace them if they aren't."
Old4New community ambassador Sue Tucker says people have come to the van with lifejackets that are 30, 40 and even 50 years old and New Zealanders need to be aware that lifejackets don't last a lifetime.
"The more old, damaged and dangerous lifejackets that are removed from the community the better."
The Old4New initiative is funded by Maritime New Zealand with support from the Southern Trust, Hutchwilco and the Giltrap Group.
