Hoteo River Kayak

Hoteo River Kayak


What do kayaking and river bank erosion have in common?


The Hoteo River is situated in the Northwest of Auckland and flows from Wellsford to the Kaipara Harbour. It is the longest river in Auckland and has the biggest catchment occupying roughly 9% of the Auckland region. The river traverses through steep hill country which is predominantly farmed before discharging through a long tidal channel by the Mangakura boat club on state highway 16.


The Stormwater Unit has commissioned Dr Andrew Simon, geomorphologist from CARDNO ENTRIX to undertake analysis of erosion potential and sediment loads associated with the river’s banks. The catchment has been flown by a helicopter to give the scientist a broad overview of the area and photographic record of reaches subject to erosion. In an effort to gain more detailed information a number of council staff, scientists and other interested parties kayaked the lower section of the river. Information on the percentage of active stream bank erosion was recorded on GPS referenced video.


All up about 20km of river was kayaked in 5 hours with a brief stop for a well-earned lunch break. Kayaking the river gave a great perspective of the river’s characteristics and the low water levels allowed the toe of the river banks to be inspected. The next phase of the research is to undertake detailed bank analysis at specific locations down the river. This information will be run through models to quantify sediment loads and erosion rates. Options with associated benefits and costs will be developed aimed at mitigating erosion and improving the water quality in both the Hoteo River and the wider Kaipara Harbour.


This research complements other work being carried out in the Hoteo Catchment by the Sustainable Catchments Programme (Environmental Services Unit) to better understand the Hoteo environment and people and to plan a catchment wide programme. It demonstrates the power of multiple teams – CLAW, stormwater and ESU working together towards the same objectives.

Skills training before next week's multiday trip with Mahurangi College. @burto1 you legend!
It's just Autumn in Auckland today #rangitoto here we come @visitauckland
Finishing the day with an epic sunset from Motuihe island. We are staying here for a multi day trip with a local high school. Amazing place to stay with kiwi, tautara to name a few 📸superguideeric
Sun's out, guns out. Stunning weather for three days of exploring the Cavalli islands in the tropical far north.
Great paddle past the Candy Cane tower (Mackenzie bay light house) while heading to Rangitoto Island. Stunning paddle with a great group of local high school students  @visitauckland
So nice to float up Williams stream in Parau on the Manukau harbor @visitauckland  thanks to @emr_nz for another amazing event
Motukorea /Browns island twilight tour. Stunning evening with a group of local friends @visitauckland @purenewzealand
Amazing adventures with a Duke of Edinburgh group last weekend. We explored loads of sea caves, learnt about sustainable journeys and the 7 steps of leave no trace @dukeofednz
Stunning morning with flat water as we got set up for another @emr_nz day. Loads of locals learning about how amazing Lake Rototoa is. For those that don't about this amazing sand dune fresh water lake which is located at the northern end of the south head of the Kaipara Harbour should go and check it out. Or even better wait until EMR runs another of their legendary experience days @visitauckland
Gift New Zealand's #1 rated guided experience this Christmas. Sunset sea kayak tour to Rangitoto Island. Escape the city to a volcanic island and see why it's a sea kayakers paradise.
