The NZ Rescue Coordination Center (RCC) has upgraded its locator beacon registration database this year, and is inviting all owners of a PLB registered before 25 February 2021 to check and update their details.

Your previous registration information is still held on file in the event of an activation, but owners moving to the new system will be able to amend the registration details themselves (In the past, you had to email changes through, which had to be manually entered by RCC staff).
