Referee David McHugh was attacked by a fan before a second half scrum in the South Africa-New Zealand game.

McHugh was flung to the ground, dislocating his shoulder and was unable to finish the match and touch judge Chris White of England took over.

In the Tri-Nations match on 3 August in Sydney, two streakers interrupted Australia's match with New Zealand just as All Black Andrew Mehrtens was preparing to take a crucial penalty kick.

"How a guy gets to run on the field and gets to a scrum without been pulled off is beyond comprehension," said Jones, perhaps in reference to the fact that 400 security staff were in attendance.

"We'd like to see those sort of things addressed.

"It is a growing concern that we're getting this unruly behaviour at rugby games and what we've got to do is legislate against it. We certainly we need to have a look at policy on ground security."

Forty-three-year-old Pieter van Zyl has since been charged with assault to do grievous bodily harm and trespassing, police announced on Sunday.

Inspector Michael Read said the spectator would appear in the Durban Magistrates Court on Monday where he was expected to make a formal bail application.

"The whole of the stadium was mal (angry) with him (the referee). It's just that I decided to do something about it," Van Zyl told the Sunday Times newspaper.

Van Zyl is from Potchefstroom, 51 kilometres southwest of Johannesburg.

Australian captain George Gregan was a victim of a pitch invasion in Rotorua, New Zealand, in May during a Super 12 match.

A teenager ran on to the field and tackled Gregan and his ACT Brumbies team-mates stepped in to pull the youth away.

Gregan believes security at all games should be stepped up, particularly with the Rugby World Cup in Australia next year.

"You shouldn't be concerned about your safety when you're actually on the field," he said.

"It's an issue that needs to be addressed and they need to nip it in the bud very quickly."
