Is it safe to swim?
About this map:
The coloured dots represent the sites "suitability for recreation grade" which is an overall water quality grade based on long-term information. It only relates to the likely health risk from faecal contamination, not toxic algae (refer to the current warnings at the bottom of this page).
Any current warnings in place at a particular site are denoted by a red flag. These warnings relate only to the latest sampling result and may indicate either high bacterial levels, a toxic algae alert or a sewage overflow warning (refer to the current warnings at the bottom of this page).
WEEKLY SUMMER SAMPLING HAS NOW FINISHED AND WILL START AGAIN IN NOVEMBER 2015. OVER THE WINTER, SAMPLES ARE TAKEN ONCE A MONTH AT COASTAL SITES ONLY.
A red alert warning for toxic algae is in place at Lower Whitby Lake in Porirua. Contact Porirua City Council on 04 237 5089 for more information.
