New Zealanders are known for our love of the water but it turns out we don't fancy jumping in.
A new survey by not-for-profit group Swim Fresh found that 62 per cent of New Zealanders had not swum once in fresh water in the last year.
Of the 1100 respondents, 79 per cent reported having visited rivers and lakes at least once and a third of those who visited in the last year went more than once a month.
Swim Fresh campaign manager Mark Blackham said that they wanted to encourage more people to use our waterways so politicians would be forced to confront the issue of water pollution.
"People profess to care about the quality of waterways but unless you get out and use them, it is easy to ignore," Mr Blackham said.
The reasons cited by the non-swimming respondents were that they either thought the water was too cold (32 per cent) or that they were concerned about water quality (29 per cent).
Mr Blackham said the campaign was also about countering the negative press about New Zealand rivers by recognising that two-thirds of our waterways are still swimmable.
The more often Kiwis visited waterways, the more likely they were to swim but those who visited were also more likely to cite water quality as a reason for not swimming.
