Thank you for your patience: the Henderson AM transmission site upgrade is complete. Over the past month, RNZ has decommissioned and replaced the 92-year-old northern mast and removed the 71-year-old southern mast at our Henderson transmission site serving the wider Auckland region. Standing at 122 metres and 153 metres high respectively this was no easy task. A crane was used to remove the old northern mast and install a new northern mast while a helicopter was required to remove the top sections of the higher southern mast before the crane was again deployed to remove the rest of the mast. The project pushed the boundaries of practical engineering, supporting 8 AM radio services from a single mast. Internationally, it’s rare to run this many AM services from one mast, with most networks opting to build additional structures instead. A complex project like this requires all teams working collectively and RNZ is thankful to the following companies that worked alongside us in the project.

Thanks very much for your patience supporting this important work that ensures resilience for the Auckland region for RNZ’s vital emergency broadcasting function.
