Hagley Park is the largest urban open space (164.637 hectares)[1] in Christchurch, New Zealand, and was established in 1855 by the Provincial Government.

[3] The boundaries of the park, which is located to the east of the central city of Christchurch, are defined by both the Avon River / Ōtākaro and the surrounding roadways.

The Christchurch Botanic Gardens (21.14 hectares) are located within this loop and frequent bridges provide connections.

[5] Hagley Park has frequently been a site for gathering large crowds together: it served as the location for the Great Industrial Exposition of 1882 and the New Zealand International Exhibition in 1906–1907.

In 1906, the Australasian tennis championships (now known as the Australian Open) were held in Hagley Park as part of the Grand Slam.

[10] Hagley Park was also the site of a national memorial service attended by 20,000 people to remember the 51 dead victims of the Christchurch mosque shootings at Al Noor Mosque and Linwood Islamic Centre which included the likes of New Zealand Prime Minister Jacinda Ardern and British Muslim convert singer Yusuf Islam (aka Cat Stevens).
