"Radio Ltd." in Auckland (and later "Radio (1936) Ltd.") were New Zealand's largest manufacturers. As well as their main brand "Ultimate" they made "Courier", "Crusader", "Hamilton", "Golden Knight", "Lewis Eady", "Luxor", "Madison", "National", "Paramount", "Rolls" and "Skyscraper" branded radios. "Ultimate" branded radios were exported to Australia from 1935 to 1940.

Founded: 1922
Production: 1923 -
"Radio Ltd." started as an importer, but by 1923 they started manufacturing radios. Their first "Ultimate" was an assembled "Gilfillan" RA-1 kitset. By 1932 though "Radio Ltd." made 20% of all the sets sold in New Zealand for that year and in 1935 made more than 9000 radios.

Geo. Brown and Co. LTD. imported ‘Ultimate’ radio receivers manufactured by Radio Ltd. in New Zealand to Australia. They were located at 267 Clarence Street, Sydney NSW.

At the end of 1935 the company moved to a large four story building in Quay St Auckland. The company was then reorganised as Radio (1936) Ltd. It continued up until 1955 when the company became Ultimate-Ekco (N.Z.) Ltd. See under this manufacturer name for more history.

This manufacturer was suggested by Stuart Irwin.
