He said that a decision on whether the car keeps the iconic Commodore name will be made "in six to eight months".
"We all know the Commodore is disappearing but we will be replacing it with a Commodore-sized vehicle," said Murray.
The 'new' Commodore will be available as a sedan and wagon.
Despite production stopping, sales of the Commodore have been strong with interest in New Zealand for the top-spec SS and Redline models.
Murray was speaking to New Zealand motoring media before the Australasian launch of the 1.4-litre turbo Holden Trax compact SUV in Melbourne today.
GM Holden Australia's new boss, Gerry Dorizas, told media at the Trax press conference that his company was committed to producing the Commodore until 2017 at its Adelaide plant.
