The Auckland regional fuel tax will be introduced on July 1 after Auckland Councillors voted 13-7 in favour of the tax this month.
Further increases will follow when the Government increases the national fuel excise by 3-4c a litre later this year, the first of three annual increases.
The Automobile Association calculates that the regional fuel tax will add an extra $126 per year for motorists in a medium-sized vehicle travelling 14,000km using 1262 litres of fuel.
Once GST is added, increasing the tax from 10c a litre to 11.5c, the annual petrol cost estimate climbs to $145 for the average user.
Hibiscus Coast commuters are expected to pay higher than the average due to the distances travelled.
