The Government today revealed its five-year more than $2 billion rebuild plan of Christchurch's earthquake-damaged infrastructure. $1.1 billion of work has been approved so far.

The city's underground pipe network and its roads were badly damaged in the intense shaking over the last two years.

Earthquake Recovery Minister Gerry Brownlee and city mayor Bob Parker unveiled the major plan at a pump station rebuild site today.

The plan includes a map setting out timeframes for roads and underground services across the city.


"This work is one piece of a much bigger and complex city-wide recovery programme," Mr Brownlee said.

"But it is highly significant as underground services need to be rebuilt and future-proofed so that the city's recovery is founded on a secure infrastructure base."

The work has been prioritised, with the aim being to fix the worst affected areas, like the eastern suburbs, first.

Mayor Parker said the plan gave "certainty for the future".
