The Government marked two milestones in its $1.6 billion Auckland rail programme today with the opening of the revamped Newmarket Station and the signing of an electrification project.

Transport Minister Steven Joyce said that after Britomart, Newmarket was Auckland's busiest station.

"Completing this project provides a new station offering all the amenities and services expected of a modern public transport facility, potential for more trains at peak times, and means fewer delays for trains coming into Newmarket," he said.

"These milestones mark progress towards a more reliable and efficient public transport network that more Aucklanders will want to use."

Mr Joyce attended the signing of the $80 million contract to build 3500 masts and portals to carry the overhead electric wires that are part of the $500 million Auckland electrification project.

"We need to get past the road versus rail debate," Mr Joyce said.

"To meet its growth projections Auckland will need all transport modes operating effectively and efficiently."

Mr Joyce said the Government was focused on both rail and road infrastructure, including the completion of the Western Ring Route, the Victoria Park tunnel and the Newmarket viaduct.
