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:
