The Transport Minister and the mayor of Auckland have clashed over a report recommending plans for the city's transport network.
Len Brown issued a statement claiming a study commissioned by Auckland Transport, said a rail link was necessary to stop the transport system from crumbling under the strain of the city's population growth.
The study warns of significant delays and congestion on all routes into the city centre within the next 10 years, said Mr Brown.
Minutes later, Gerry Brownlee responded in a statement, saying a tunnel is not viable.
The City Centre Future Access Study was carried out in an effort to develop an achievable transport programme for access into the city centre.
