Tutaekuri River

The Tutaekuri River rises in the Kaweka Ranges and crosses the Heretaunga Plains to flow into the Pacific.  It shares a river mouth with the Ngaruroro River and the Clive/Karamu.  

The Tutaekuri catchment supports significant ecological values associated with the aquatic and riparian ecosystems and significant habitats of indigenous fauna and flora. The catchment supports a regionally significany brown and rainbow trout fishery. The angling activity is spread throughout the catchment, with the Tutaekuri main stem the most sought after fishery. The trout populations in the catchment are self sustaining, with trout spawning occurring in a number of tributaries. 

Recreational activities, such as swimming canoeing/kayaking and fishing occur along the river and there is a camping site near Dartmoor.

The catchment is included in a new plan change being developed to cover the Greater Heretaunga Plains which includes the Tutaekuri, Ahuriri, Ngaruroro and Karamu catchments.

Scientific Indicators
Scientific data for this catchment

This dashboard shows information on the data collected by the regional councils for water quality indicators, analysed as state and trend.

The state for the catchment is represented by the median concentration for the parameter across all sites within the catchment and then compares that value to the quartiles for all monitored sites in New Zealand.

Click on the parameters state icons to compare this catchment with others in the region.

  • State

    State shows how the median of samples from this site compares to other sites

  • Trend

    Trend shows how the quality of water is changing over time. Depending on the sampling history duration, five and ten year timescales are available:

Can I trust this data?

The Cawthron Institute has worked alongside regional councils to verify the processes and methods used for data collection, laboratory analysis of samples collected and the statistical analysis and interpretation of the results presented.

If all Cawthron ticks are green, then you can trust this data. However, if one or more ticks are orange, then conclusions should be treated with some caution.

For more details on each tick, see our 'Can I Trust This Data?' Factsheet.

Data Collection

All samples were collected using approved field protocols and have been analysed in accredited laboratories. Therefore the data shown here has been collected and analysed following best practice.

State

All samples were collected using approved field protocols and have been analysed in accredited laboratories.

Trend - SAMPLING FREQUENCY

Samples are collected monthly, bimonthly and quarterly in this region. Proposed national guidelines suggest monthly sampling is required for trend analysis. Therefore, any trends shown here are less robust than those calculated from data that is solely collected monthly. New Zealand's councils are currently reviewing their sampling procedures and aim to adjust their sampling frequency to monthly for all sites. This will increase the robustness of the trend analyses

Trend - Adjustment for flow

This data is not flow adjusted. National guidelines suggest that flow-sensitive variables are flow 'adjusted' before trend analysis. Therefore, any trends shown here may be affected by variations in flow across sampling occasions.
