Waltham, New Zealand

Waltham is an inner suburb of Christchurch, New Zealand, located approximately 2 km 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.

Approximate boundaries of the suburb are Waltham Road, Moorhouse Avenue, Ferry Road, Ensors Road, and the Ōpāwaho / Heathcote River. Waltham was originally part of the Sydenham borough and was incorporated into the City of Christchurch in 1903 when the borough was ended. In the early 1980s local residents and the Christchurch city council tried to name the western part of the suburb, Charleston, between Ferry Road and Ensors Road. This was done to maintain the residential nature of the area against perceived industrial expansion. The attempt was partly successful and that area today is referred to as both Waltham and Charleston.

The full suburb is a mixture of residential and both light and heavy industry.

History
An early Christchurch settler, Charles Prince, owned a large house, called Waltham House, on nearby Colombo Street South. 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.

The Christchurch gasworks was located at the inner boundary of Waltham until its closure around 1980.

Waltham was home to a malt works and a collection of warehouses on Waltham road. These were demolished and redeveloped into 88 two and three bedroom townhouses after the 2011 Christchurch earthquakes.
