Information on the Kaituna River and Ongatoro/Maketu Estuary Strategy

The Regional Council has a number of projects that help implement the Strategy, including the Kaituna River Re-diversion Ongatoro/Maketū Estuary Enhancement Project.

Project goal and objectives

The goal of the Kaituna River Re-diversion Ongatoro/Maketū Estuary Enhancement Project is to significantly increase the volume of water (particularly fresh water) flowing from the Kaituna River into Ongatoro/Maketū Estuary by 2018 in a way that maximises the ecological and cultural benefits (particularly wetlands and kaimoana) while limiting the economic cost and adverse environmental effects to acceptable levels.

Project objectives

1. To work in an open, transparent and fair way that engages tangata whenua, the local community and other stakeholders and recognises their views and aspirations.

2. To determine the optimal path, volume and configuration of a Kaituna River re-diversion option that maximises ecological and cultural benefits while limiting economic costs and environmental effects to acceptable levels by modelling, expert advice, published literature and of pre-consent community consultation by February 2014.

3. To determine the optimal location, size, function, cost and restoration potential of at least 20 hectares of new wetlands to be created during the implementation of the re-diversion by February 2014.

4. To lodge applications for any consents, designations or other permissions required to achieve the project goal by June 2014.To obtain all consents, designations, permissions and land required to achieve the project goal by October 2015, subject to legal processes.To begin the staged implementation of consented works by October 2015.

5. To complete consented capital works by June 2018, subject to completing consenting and land acquisition processes.

6. To seek opportunities to achieve the non-funded actions in the Kaituna River and Ongatoro/Maketu Estuary Strategy through other council programmes or partnerships without compromising achievement of objectives 1 to 7, where such opportunities arise.

7. To report publicly on progress against all actions in the Kaituna River and Ongatoro/Maketu Estuary Strategy by 31 August each year.

The four key outcomes sought are:

  • Improve water quality
  • Restore healthy ecosystems
  • Ensure sustainable resource use
  • Support kaitiakitanga and local people's stewardship
