The Hack Circle or Hack was a nickname given to an amphitheatre in central Christchurch, New Zealand. It was built as part of the second phase of developing a pedestrian mall in the central city in 1989 and was officially opened on 6 December of that same year by then mayor Vicki Buck. For a time it was a popular Hacky Sack venue, later it became a popular hang out for "black-dressed emos, goths, heavy metal fans and United States style gangstas". A 2004 survey conducted by the Christchurch City Council identified the Hack Circle as a popular place for young people to "hang out, smoke, meet friends etc." The same survey found that 90% of 13- to 15-year-olds and 94% of 16- to 18-year-olds came to the central city in their spare time.
