Mairangi Creek in Auckland’s North Shore was engulfed by three-metre high bubbles on Sunday afternoon, Stuff reports. Hibiscus and Bays local board member Julia Parfitt said incidents like this are not unheard of during the school break. “We get things like this sometimes in school holidays with children or other people putting dye and detergent in waterways, not realising that it can affect the pH level of the waterway and lead to the destruction of wildlife in the waterways.” The foam travelled more than a kilometre to reach the beach.
