September 2018This report has two sections: Section 1, facilitated by Te Ātiawa Manawhenua Ki Te Tau Ihu Trust, describes the history and cultural values associated with the Waitohi and Waikawa streams. Section 2, an interim report by the Marlborough District Council, addresses Water Quality in the Waitohi and Waikawa catchments. This work will be used to inform future work that both parties can undertake in these catchments. Read more -
September 2018The Ministry for the Environment commissioned this research to identify perceived barriers to the adoption of any of the three mechanisms proposed in the draft plan change for the Tutaekuri, Ahuriri, Ngaruroro and Karamu catchments (known as ‘TANK’). Read more -
September 2018This report offers preliminary guidance to water management groups(WMGs), regional councils and other interested parties on how WMGs can be structured and what regional council plans should contain to improve the likelihood that groups will achieve the freshwater outcomes desired by their communities.

August 2018This technical guidance will help councils with the process set out in the Periphyton Attribute Note in the National Policy Statement for Freshwater Management 2014 (as amended 2017). Read more -
August 2018Trend analyses performed on many sites are regularly aggregated by water quality variable and summarised in tabular, graphical or map format as part of environmental reporting. Read more -
May 2018This report outlines the establishment of reference conditions and trigger values. Reference conditions are defined as the chemical, physical or biological conditions that can be expected in streams and rivers with minimal or no anthropogenic influence. Read more -
May 2018Phormidium is a potentially toxic, mat-forming benthic cyanobacterium found in an increasing number of New Zealand rivers. This report outlines a study which assessed Phormidium toxin levels in the Cardrona (Otago), Mataura (Southland) and Hutt (Wellington) Rivers in 2017. Read more -
May 2018The Managing Upstream project aims to help inform management decisions when establishing freshwater objectives under the Freshwater NPS and increase knowledge on the state of different estuary types in New Zealand. Read more -

May 2018Phormidium is a potentially toxic, mat-forming benthic cyanobacterium found in an increasing number of New Zealand rivers. This report outlines a study which investigated drivers of Phormidium blooms in New Zealand rivers to predict risk of blooms. Read more -
May 2018This report provides an environmental classification system for a potential deposited sediment indicator in the National Objectives Framework. The system classifies streams according to their modelled reference state. This report is an interim deliverable for an ongoing research programme that builds on and refines its findings and will conclude in June 2018. Read more -
May 2018This research assesses the applicability of environmental classification systems for a potential suspended sediment indicator in the National Objectives Framework. It evaluated the relationship between modelled suspended sediment indicator values and observed values, land cover, and River Environment Classification typologies. This report is an interim deliverable for an ongoing research programme that builds on and refines its findings and will conclude in June 2018. Read more -

February 2018An independent report has shown that water quality for sediment and E. coli have improved over the past 7-10 years in the Horizons Region. There are encouraging signs that local scale interventions are collectively contributing to regional scale water quality improvements. The case study, conducted by Land Water People Ltd and reviewed by NIWA and StatsNZ, was commissioned jointly by the Ministry for the Environment and Horizons Regional Council as a way to understand improving water quality trends in the Manawatū-Whanganui Region.
