Monitored sites in the Tutaekuri River catchment
Filter sites by:
No sites found.
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.

Trend shows how the quality of water is changing over time. Depending on the sampling history duration, five and ten year timescales are available:
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.
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.
All samples were collected using approved field protocols and have been analysed in accredited laboratories.
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
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.
