The plan called for hapu to investigate mangrove management and identify areas where mangroves should be removed.
Land management practices should also be improved to reduce stormwater discharge sediment entering the harbour.
Hapu will seek a formal agreement with the Department of Conservation to manage Mount Maunganui's two off-shore islands of Moturiki (Leisure Island) and Motuotau (Rabbit Island).
The hapu management plan said Matapihi needed to keep its rural character and not be included inside Tauranga's urban boundary.
An environment unit could be set up to deal with issues such as the plan being implemented in local and regional council planning and resource consent processes, and raising funds for environmental enhancement projects.
Hapu also wanted to become more proactive in dealing with issues such as noise pollution and chemical pollution such as toxic sprays.
