LAWA is the most comprehensive and up-to-date source of recreational water quality information for New Zealand. LAWA provides this information so you can use it as a guide to decide where and when to swim. Please note that water quality monitoring results are representative at the time of sampling. Water quality can change over time, especially during periods of significant rain or unexpected pollution events. This is why we recommend that you avoid swimming for 2 - 3 days after heavy rain, even at sites that usually have good water quality. If you are unsure, please check with the relevant council or choose another site to swim. Water quality results from weekly monitoring are not intended to provide a guide on suitability for swimming outside the recreational bathing season. LAWA takes no responsibility for the accuracy of information presented, and accepts no liability for actions taken of others based on this information.
