In 1975, the NZBC was broken up with Wellington and Dunedin studios taking over NZBC TV as Television One while Auckland and Christchurch studios launched Television Two. At the same time, the Wellington studios moved to the new purpose-built Avalon Television Centre in Lower Hutt. In 1980, Televisions One and Two merged under a single company, Television New Zealand (TVNZ). The majority of television production moved to Auckland over the 1980s, culminating in the opening of TVNZ's new Auckland television centre in 1989.
