Nearly $30 billion will be spent on Auckland transport in the next 10 years, partly funded by a fuel tax, private finance and tolls.

The government and Auckland Council have announced the new Auckland Transport Alignment Project (ATAP) at Newmarket train station today.

Watch the announcement here:

Billed as New Zealand's largest ever civil construction programme, $28 billion will be poured into light rail and roading projects at Penlink and Mill Rd.

Heavy rail and bus upgrades, safety improvements and more dedicated cycle lanes are also part of the plan.

The projects will be funded by $4.4 billion raised from the new Auckland fuel tax, increased revenue the National Land Transport Fund and Crown Infrastructure Partners contributions.

Transport Minister Phil Twyford said the funding plan also included public private partnerships.

"We're putting half a billion dollars into Mill Rd which is going to take a lot of pressure off the Southern Motorway between Manukau and Drury, and $200 million into Penlink, which we're intending to do as a PPP. It's perfectly designed as a toll road," Mr Twyford said.

Auckland Mayor Phil Goff said $1.8 billion was set aside for light rail but extra funding would be announced shortly.

He said a fuel tax was a better option than raising rates.

"Auckland has to contribute its share and the regional fuel tax allows us to do that. The more than $4 billion expenditure it unlocks is critically important to progressing a better transport system for Auckland.

"To raise the same sum from rates would result in a total rate increase of over 13 per cent this year. Alternatively, to do nothing would see Auckland become increasingly gridlocked."
