A number of people were evicted from the ICC Cricket World Cup 2015 opening match at North Hagley Park in Christchurch yesterday for courtsiding.
Courtsiding refers to the practice of spectators within venues relaying information of incidents during games to people overseas, taking advantage of broadcasting time delays to manipulate betting.
It is different from match-fixing, which is the manipulation of sporting events to achieve a pre-determined outcome.
While courtsiding is not illegal in New Zealand, it is a breach of the terms and conditions of ICC Cricket World Cup 2015 tickets.
ICC Cricket World Cup 2015 policing operation commander Sandy Manderson said police knew how to identify people who were courtsiding and those attempting it would be caught.
