Albert-Eden-Roskill reporting area

Includes Albert-Eden and Puketāpapa local boards

State of Auckland


Area Grade


July 2014

What makes up this grade?


The overall grade is made up of five indicators:

Water quality: Water samples are tested for temperature, oxygen concentration, turbidity and the levels of pH, ammonia and nutrients (nitrogen and phosphorus). The results of this testing are compared against guidelines for Auckland to produce a water quality index.

Flow patterns: This involves monitoring the hydrologic connectivity of the river to upstream and downstream reaches and the floodplain using the Stream Ecological Valuation (SEV), which is a method of assessing the ecological health of our rivers.

Nutrient cycling: This involves monitoring the inputs and processing of minerals, particulates and contaminants using the SEV biogeochemical functions.

Habitat quality: This involves monitoring the diversity and quality of habitats using the
SEV habitat provision functions.

Biodiversity: Field assessments and samples are collected to assess the type and amount of native plants and animals using the SEV biodiversity functions.

Quick facts

The reporting area covers 47KM2 representing 1% of the region 

The land cover is mainly urban (94%) with small pockets of native, exotic and pastoral vegetation

The extent of impervious surface (hard surfaces) is very high (55%) when compared with the regional average of 9%


Albert-Eden-Roskill monitoring sites

Monitoring background and interpretation

Auckland Council’s State of the Environment (SoE) monitoring programme has been building a record of Auckland’s environment for more than 25 years. This information is critical to the effective management of Auckland’s natural environment, after all, you
can’t manage what you don’t monitor.

The monitoring programme shows there is a strong relationship between the health of rivers and the type of land cover in the surrounding catchment. Rivers that drain through forested catchments (particularly native forests) typically have excellent water quality and ecology, while rivers that drain from urban catchments typically have poor water quality and ecology.

The health of the Albert-Eden-Roskill area’s rivers is considered to be impaired. Urban development has led to a high level of impervious (hard) surface in the area, which prevents rainfall from soaking into the ground. This has follow-on effects for rivers
in the area leading to high water temperatures, changes to the natural flow patterns and increased pollution from contaminated stormwater.

Wai Care is a water quality education, monitoring and action programme managed byAuckland Council, for schools and community groups in the Auckland region.

The programme aims to educate people about freshwater issues and encourage and facilitate action in the local community, from water quality monitoring to streamside planting and litter clean-ups.

The following table show achievements of the Wai Care Programme in Albert Eden and Puketapapa during the 2013/2014 financial year.



Wai Care has been actively involved in restoration and monitoring of the Meola and Oakley Creek during 2013/14. The Meola Creek runs from Mt Albert to the Waitemata Harbour and has been heavily impacted by urbanisation. The Oakley Creek runs from Mt Roskill to the Waitemata Harbour. Wai Care works with local community groups to help monitor water quality and undertake restoration planting along the creeks.
