Sound Group has been the New Zealand distributor for Yamaha hi-fi since 1983, and it is a wholesaler, so the customers are shops and installers rather than the public. The business began in 1979 making speakers for a North American brand, and it still sells to the trade across the country. Its portfolio now covers market-leading brands for custom installation, along with other hi-fi and home theatre products. Its own description says it distributes brands that lead the way to specialist installers throughout New Zealand. The company calls itself 100% New Zealand owned and operated, with its staff, offices and warehousing all based here. It works from Rothwell Avenue in Rosedale on the North Shore, in an industrial pocket of Auckland's north. If you run an audio or home theatre shop, or install systems, this is the kind of supplier that stocks the brands your clients ask for. Anyone else will need to go through one of its retailers or installers.
