NSL Case Study | TVNZ

About TVNZ

Television New Zealand, more commonly referred to as TVNZ, is a crown-owned, commercially funded broadcaster operating television channels and streaming services in New Zealand and providing technical delivery for the Pacific Cooperation Broadcasting Limited and their service in the Pacific region. TVNZ is one of the leading broadcasters in New Zealand, with revenues earned through advertising. TVNZ currently operates channels TVNZ 1, TVNZ 2, and TVNZ DUKE, including online entertainment destination TVNZ OnDemand.

Project Brief


Due to the new presenting style adopted by TVNZ, the presenters are no longer confined to a desk and require the freedom to move around the room during the broadcast, whether it be in front of a large screen or moving around an augmented reality set. The new look and style for the TVNZ presenters require a more compact bodypack with less weight, which enables more movement as well as the equipment being invisible to the viewers. TVNZ requires the presenter to be able to move from the main studio to the newsroom and the ability to be remote for outside news feeds without the changing equipment packs.


NSL conducted multiple RF scans within the broadcast studio, newsroom of TVNZ. Utilising Shure Wireless Workbench 6 Software and the Axient AXT600 spectrum manager. The RF scan data concluded that Shure Axient would meet and exceed the requirements in the project brief. WWB6 was also used to coordinate frequencies between the Axient system and PSM900 systems which would be used for interruptible foldback.


The ADX1M was chosen due to the small size of the micro packs, internal antenna, and ShowLink ability. The AD610 ShowLink unit utilises Wireless Workbench 6 giving the sound engineer full control and monitoring of the system remotely. The ability to change frequencies on the fly and adjust gain settings was seen as a must have add-on to the system for TVNZ.

UA874WB paddle antennas were deployed in the studio and split out to the newsroom so presenters can broadcast from both locations without the need to change out equipment. Audio from both zones is fed back to the central control room. Battery management is handled by the networked SBRC battery charger units with modules for both the Axient and PSM batteries. Battery charger monitoring is also handled by WWB6 giving health, time to charge, and temperature status.

Axient Wireless System


Shure Battery Rack Charger interchangeable charging modules support a variety of Shure Lithium-ion batteries accommodating up to eight batteries in a single rack space. The rechargeable battery system provided a sustainable and cost-efficient solution for TVNZ. With Shure Wireless Workbench software, it can provide remote monitoring of battery status when the SBRC is connected to a network.
