AA Insurance was launched on the 15th of August 1994 as a joint venture between GIO Australia and the New Zealand Automobile Association. The goal of
AA Insurance was to provide AA Members with a range of insurance products tailored to specifically meet their needs.
In 2002, a new joint venture partner, Royal & Sun Alliance Insurance (New Zealand) Limited, acquired a 68% shareholding in AA Insurance Limited.
In 2003 Royal & Sun Alliance altered its organisational structure and listed on the New Zealand stock exchange as Promina. Royal Sun Alliance (New Zealand Limited) re-branded under the name Vero Insurance (New Zealand) Limited and is an integral part of the Promina family, which is New Zealand's largest composite insurance Group. Vero Insurance (New Zealand) Limited, and the New Zealand Automobile Association, are joint venture partners for AA Insurance Limited.
In March 2007, Promina was bought by Suncorp, in the second biggest deal in Australian Financial Services history. This enables AA Insurance to be part of a top 20 ASX-listed group, with all the advantages this partnership brings.
