Dan and colleagues from Ecomatters Trust had a steady stream of visitors to their pop-ups on the edge of the lagoon. They were talking to locals and offering free assessments of septic tanks. People could fill out a survey form about their knowledge and interest in fixing the problem of polluted lagoons.

Ecomatters staff were also testing people support for various slogans and poster styles and finding out about people’s knowledge of what parts of Piha might be creating the pollution problems at both Piha and North Piha.

This “open day” is to be followed by a door to door visit to properties offering support and free tests.
