Christ Church Cathedral, Anglican cathedral in Nelson, New Zealand

Christ Church Cathedral is an Anglican cathedral at 1 Trafalgar Square in Nelson, New Zealand. Completed in 1965 in a Modernist Gothic Revival style, it is 58 metres long and 27 metres wide, with a 35-metre tower and seating for 350 people. Its walls incorporate marble from the Pakikiruna Range, ground and mixed with plaster after the 1929 Murchison earthquake made block use too risky and expensive.

The first church on a different site was built in 1851 to a design by Frederick Thatcher and enlarged in 1859; in 1866 it was named Christ Church Cathedral and enlarged again. Construction of the present building at 1 Trafalgar Square began in 1925 and finished in 1965, and Bishop Peter Sutton consecrated it on 14 April 1972.

The cathedral is the seat of the Bishop of Nelson, currently Steve Maina, and the mother church of the Diocese of Nelson. Its name comes from the original 1851 church, which was renamed Christ Church Cathedral in 1866. The building was consecrated by Bishop Peter Sutton on 14 April 1972.

The cathedral stands at 1 Trafalgar Square, up the hill from Trafalgar Street, and seats 350 people. The granite steps came from Tonga Beach in Tasman Bay, and a monument above Trafalgar Street marks 100 years of Nelson settlement. Entry is from the square; the building is an active Anglican parish church, so visits may be limited during services.

The marble cladding was meant to be laid in solid blocks, but after the 1929 Murchison earthquake that was judged too risky and costly, so the Pakikiruna Range stone was ground and mixed with plaster, giving the walls their unusual colour. The granite steps came from Tonga Beach in Tasman Bay.
