An amateur astronomer’s ambition still points at the sky from the edge of Cooks Gardens. The Ward Observatory on St Hill Street, central Whanganui, is a small domed building that houses a second-hand 9½ inch refractor telescope brought out from England for the local astronomical society.
Heritage New Zealand describes it as one of the oldest observatories founded by an amateur that survives in New Zealand, and lists it as a Category 1 historic place. Whanganui District Council owns the building, and the Wanganui Astronomical Society still meets there and opens it to the public on Friday nights.

About the Ward Observatory
The observatory carries the name of Joseph Thomas Ward, an amateur astronomer who lived from 1862 to 1927. In 1901 he was instrumental in forming the Wanganui Astronomical Society and became its first president.
The new society soon found its telescope. In 1902 it acquired a second-hand 9½ inch refractor that had been built in England, and a building was then designed to house it. The architect Alfred Atkins drew up the observatory from plans supplied by Ward, and Russell and Bignell built it.
Premier Richard Seddon officially opened the observatory on 25 May 1903, and Ward was appointed its honorary director. Working with his assistant Thomas Allison, Ward studied double stars, and some of their observations are still recognised in international catalogues as “Ward doubles”.
The observatory later passed to the city council, and Whanganui District Council still owns it today. The facilities grew in 1952, when a lecture room and toilets were added, and in 1979 and 1980 the council heavily modified the opening in the dome.
The Telescope
The 9½ inch refractor at the heart of the building is the same instrument the society bought in 1902. Heritage New Zealand includes the telescope and its mounting in the listing, which is why the entry is named Ward Observatory (Including Telescope and Mounting). The Wanganui Astronomical Society still uses it regularly.
Viewing Nights
The Wanganui Astronomical Society runs public viewing at the observatory on Friday nights. The council notes that viewing is weather permitting, so check the society’s listing on New Zealand Astronomy before you head out.
