Demolition on the earthquake-damaged Lyttelton police station, New Zealand's oldest, will start on Monday.
The Italianate-style building was built between 1880-1882 using Lyttelton prison labour, and was the oldest and longest continually used police station in New Zealand.
Extensive damage in the February 2011 quake meant that the building was deemed unsafe to occupy, and repairing it would be uneconomical. It would cost $350,000 more to repair the building than a complete rebuild.
The cell block at the rear of the station dates back to the 1920's, and will remain untouched on site until it finds a new home.
Several items with historic significance will be salvaged, including the archways, etched glass panels, wooden staircase and balustrade, and these may be used in future police stations.
