Waipaoa River

For a Waipaoa water allocation, low flow monitoring occurs from the Waipaoa River at Kanakania Bridge. 

The Waipaoa River water quantity zone for the Waipaoa Catchment plan includes: 

• A Block allocation cap of 2000 l/s (instantaneous take) starting at 1300 l/s.

•  B Block allocation cap of 2000 l/s (instantaneous take) starting at 4000 l/s.

This means if you have a B Block Waipaoa allocation, you must stop using water when the flow at Kanakania reaches 4000 litres per second.

For an A Block Waipaoa allocation you must stop at 1300 litres per second. 

Te Arai River

For a Te Arai water allocation, low flow monitoring occurs at Pykes Weir.

• A Block allocation cap of 70 l/s and a minimum flow of 60 l/s.

B Block allocation cap of 100 l/s and a minimum flow of 220 l/s.

This means if you have a B Block allocation, you must stop using water when the river flow reaches 220 litres per second.

If you have an A Block allocation, you must stop at 60 litres per second.

If you continue to take water when under low flow restrictions, you will be in breach of your consent and action will be taken to ensure you comply.
