Children's rash vests that unzip to reveal clear CPR instructions are on sale to Kiwis, who by purchasing the swimwear can also support their region's rescue helicopter.

The rash vests are on offer via Westpac NZ, which aims to help Kiwi families to stay safe around the water this summer.

Designed to fit children aged two to eight, the Westpac Rescue Rashies provide potentially life-saving information in a rescue situation, and remind families about the importance of water safety.

The bank is giving away about 1000 Rashies to Kiwi kids around the country during the next few months. The remaining 7000 are on public sale, with 100 per cent of the $25 purchase price going to the local rescue helicopter of the purchaser's choice.

Westpac NZ CEO Catherine McGrath says too many NZers are drowning, and the bank wants to work together with Kiwis to turn things around.

'There were 90 preventable drownings in 2021 – the highest in 10 years – and drownings are on track to rise again this year,” says Catherine.

'Reminding ourselves about how vigilant we all need to be near and in the water is really important as we start to enjoy the great NZ summer.”

In addition to featuring a unique fold-back design to display CPR instructions, Rashies are brightly-coloured, making children easy to spot, and offer UPF50+ sun protection.

Westpac ambassador Dame Sophie Pascoe, is right behind the campaign.

'What I love about Rescue Rashies is they're a fun and interactive way to remind us about water safety. Kids love wearing them, so putting them on doesn't feel like a chore," says Sophie.

'Every kid wants one and Westpac has ordered more to keep up with demand. I look forward to seeing lots of these Rashies around our rivers, lakes and beaches this summer and in future.”
