Waltham is an inner suburb of Christchurch, New Zealand, located approximately 2 kilometres (1.2 miles) south-east of the city centre.

State Highway 76, part of Christchurch's ring road system, and known there as Brougham Street, runs through the suburb, as does the Lyttelton Line rail corridor.

This was done to maintain the residential nature of the area against perceived industrial expansion.

[3] The attempt was partly successful and that area today is referred to as both Waltham and Charleston.

[citation needed] The full suburb is a mixture of residential and both light and heavy industry.

In 1866, a meeting of local residents was held at the house and it unanimously agreed to name the district of the present day suburb, Waltham.

[9] The Lancaster Park statistical area covers 1.12 km2 (0.43 sq mi).

[15] The Waltham swimming pools were badly damaged in the 2011 Christchurch earthquakes.

The pools were reopened in January 2015 after repair work that was estimated to cost $3.2 million dollars.

Repair work included upgraded signage, a re-sized plant room, fencing, painting, landscaping and roofing,[16][5] The outdoor pools are open over summer each year.
