The Auckland Council is preparing a rearguard campaign to retain provisions for regional fuel taxes to help pay for transport projects such as its $2 billion-plus underground railway scheme.
It is likely to seek support from other regions - transport committee chairman Mike Lee says the campaign is about self-determination and "not just about Auckland".
"I'm aware that every region in the country is looking for extra funding sources for transport projects," he told the committee at its monthly meeting.
His committee has endorsed, if only by a 5-4 majority, a consultants' study as ammunition against a Government plan to repeal legislation which allows regions to raise their own fuel taxes - although subject to Beehive approval.
The study by the Ascari and Berl economic consultancies has concluded that administration costs and a risk of local taxes spreading to other regions as feared by the Ministry of Transport can be minimised.
