Pascall products were first produced as a joint venture between the Cadbury Brothers and James Pascall at the Cadbury factory in Tasmania, Australia. In 1938, Pascall products commenced production in New Zealand. In 1981, Australian Pascall production moved from Tasmania to Melbourne. In New Zealand, most of the products produced by Pascall were made at their own factory in Avondale, Auckland until December 2009, when the factory was closed down and production moved to the Cadbury factory in Dunedin and to factories in Australia and Thailand. The response to the changes has not been popular with New Zealanders, claiming that the Thai made Minties are much softer and do not taste the same.
