The water quality of 350 beaches around New Zealand is now accessible online.
The national monitoring website launched in March monitoring data of over 1100 river sites around New Zealand and that is now being extended to coastal waters.
"I want the millions of New Zealanders who go to the beach to swim, surf and play to have access to good information on water quality," Environment Minister Nick Smith says.
"It enables people to stay healthy and raises awareness of the importance of improving our water quality."
New Zealand beaches generally have good water quality for swimming with 64% having low or very low risk, 22% an acceptable standard and 14% having high risk.
Mr Smith says the move is about giving integrity to New Zealand's clean green brand and highlighting areas where communities need to do better in managing water quality.
