Private Law - Cricket edition

Cops moonlighting, out of uniform, as event security - I can get that.

This one I'm less clear on:

Police have warned people who try to manipulate betting on the ICC Cricket World Cup 2015 that they will be caught and banned from all grounds involved in the tournament.

Police evicted several people from the opening match at North Hagley Park in Christchurch today for breaching the terms and conditions of their tickets, including some who were caught "courtsiding".

So what criminal offences are these courtsiders committing?

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.

Courtsiding is not illegal in New Zealand, but it is a breach of the terms and conditions of ICC Cricket World Cup 2015 tickets.

Operation Commander for the ICC Cricket World Cup 2015 policing operation Superintendent Sandy Manderson said Police knew how to idenfity people who were courtsiding and those attempting it would be caught.

"We know what to look for.

We’re aware that people are attempting to operate at venues and they will be detected, evicted and trespassed from all venues. 

So the New Zealand Police are enforcing the terms and conditions of the ICC Cricket World Cup tickets. I could get their enforcing trespass where the venue kicked somebody out for breach of conditions, but why are the Police investigating breach of ticket terms and conditions?

If you were at the venue and didn't know that Sky had gone to commercial, would tweeting a 6 or a wicket get you kicked out of the match by the cops?
