Do your bit to protect the lakes and rivers that you love.
All it takes is one tiny fragment of hornwort or a single freshwater gold clam. If aquatic pests hitch a ride on your gear they can spread to previously unaffected waterways - choking our lakes and rivers, make them murky, and out-competing native wildlife.
Rules for boat ramp users
The Bay of Plenty Regional Pest Management Plan 2020–2030 requires that all boat ramp users check, clean, dry and certify that their boat is free from freshwater pest fish and weed.
We ask that you familiarise yourself with the rules and ensure that you comply with them when heading out on the water.
Bay of Plenty Regional Council Regional Pest Management Plan 2020 – 2030 Rule 7
- No person shall leave boat trailers in any water body other than for the purposes of launching and/or retrieving boats.
- No person shall transport ballast water from any water body to any other location.
- All occupiers of vessels or craft entering any water body within the Bay of Plenty shall ensure their vessels or craft (including trailers) are free from freshwater pest fish and freshwater pest plants including fragments.
- All occupiers of vessels or craft using a boat ramp with a self-certification checkpoint must complete a self-certification form*. Before launching the self-certification form must either be submitted electronically or displayed in the vehicle used to launch the vessel or craft.
*Electronic self-certification forms are available at boprc.govt.nz/ccd-self-cert. Paper self-certification forms are available either at the self-certification checkpoint or the Bay of Plenty Regional Council offices.
Biosecurity staff will be visiting boat ramps throughout summer to help lake users understand the rules and check that they are complying with them. Lakeside self-certification checkpoints, with instructions, have been set up at boat ramps around the Rotorua Te Arawa lakes.
Ways to self-certify:
- Online form.
- Paper form at boat ramps or Regional Council Offices.
- QR codes at boat ramps that link to the online form.
- Print out and complete the form if no forms are available at the boat ramp.
How to Check, Clean, Dry
Check
- Remove any visible matter, including any clams you can see, along with plant material or mud. Drain all river or lake water.
Clean
- Washdown your gear, vehicle, watercraft, and trailer that has been in contact with river or lake water with tap-water onto grass, beside the waterway or at home and not into a stormwater drain system. This will remove any remaining invisible material.
- For absorbent surfaces and materials that have been in contact with river or lake water (including carpet on trailers) use an appropriate treatment in the treatment options table on the MPI website.
- Treat residual water that always occurs when on-board ballast bladders or tanks have been pumped.
