Pest warning: Mediterranean Fanworm

The Mediterranean Farmworn is a pest which has been spotted in the Waitemata Harbour / inner Hauraki Gulf, as well as the Whangarei Harbour and Lyttleton Port.

Keep your boat's hull clean to reduce the risk of this pest clinging and causing damage to our marine life.

Marine Biosecurity Information: New Rules & Regulations

Marine pests spread easily through ballast water and hull fouling, including Mediterranean fanworm (Sabella spallanzanii) and Clubbed tunicate (Styela clava). Check to ensure your hull is clean and be aware of other regions rules before leaving Auckland.

Maritime VHF Channels: changes from 1 October 2016

New Zealand, along with a number of other countries, is required to change some maritime VHF repeater channels to make space for newly allocated international services for ship-tracking and data services.

New Zealand will be moving a few private VHF repeater services, most Coastguard VHF repeater services, and all NowCasting weather services to accommodate these changes.

The frequency changes will take place in New Zealand on 1 October 2016, before the peak summer recreational boating season when VHF radio services become busy. This ensures New Zealand is ready for the changes that come into force internationally on 1 January 2017.

For more information and to find out which repeater and weather forecast channels you should be using from 1 October:
