Zone committee recommendations

The OTOP Water Zone Committee has developed a package of recommendations called a Zone Implementation Programme Addendum (ZIPA), for regulatory and non-statutory actions to improve water quality and quantity, as well as biodiversity and tāngata whenua values in the zone.

Since 2016, public meetings have been held throughout the region to discuss water management priorities. The feedback from these meetings – including the outcomes expected by the community - helped guide the committee’s 100 plus recommendations to councils and stakeholders, released in December 2018. These recommendations form an Addendum to the Zone Implementation Programme (PDF File, 4.85MB) that was developed with the community in 2012.

The priorities of the ZIPA include the provision of safe drinking water, protecting mahinga kai and sites of cultural significance, protecting native plants and their habitat and maintaining a reliable source of water that contributes to the economy.

Reports on ecological flow, economics, water quality, and culture

In this comprehensive collection of technical reports spanning several years, diverse aspects of the Ōrāri Temuka Ōpihi Pareora (OTOP) Zone's environmental management are meticulously examined. Covering ecological flow assessments, economic evaluations, water quality investigations, and cultural values, these reports provide a thorough exploration of the current state, alternative pathways, and potential solutions sought for sustainable water resource management in the region.
