Key Auckland transport projects have received a boost under the Budget 2014 through a $375 million interest-free loan to the NZTA.
In his Budget speech, Bill English said the loan would accelerate $815 million worth of Auckland transport projects.
Transport Minister Gerry Brownlee said the projects would address congestion the country's largest city, improve access to Auckland International Airport and capitalise on the benefits of major roading projects already under way - including the Western Ring Route.
"No Government has invested so heavily in transport infrastructure across all transport modes," he said.
"But with freight demand forecast to grow by around 50 per cent across the country in the next 30 years, and by almost 80 per cent in Auckland, and with a growing population, we've decided to bring a number of important projects forward.
"Some of these projects were up to a decade from starting, but we've decided they simply must begin sooner to give Auckland the best opportunity of moving people and goods around the region."
The $375 million will be transferred to NZTA as an interest-free loan, to be repaid to the Crown by funding currently allocated to these projects in the National Land Transport Fund up to 2026/27, Mr Brownlee said.
The Government has also announced today that $32.7 million of new operating funding will be allocated over the next four years in the Budget to cover the debt financing cost to the Crown of the interest-free loan.
