The Otago Rugby Football Union, along with police, the Dunedin City Council and the New Zealand Rugby Union issued a statement yesterday, saying it would have zero tolerance towards negative behaviour at Carisbrook this season.
ORFU operations manager Coryn Huddy said it had discussed the policy with Dunedin Venues Management Ltd chief executive David Davies.
However, no decision had been made on such bans with regards to the new Forsyth Barr Stadium.
An alcohol ban at Carisbrook had also been considered but it had been decided to continue selling liquor at the ground.
At the first test match at Carisbrook for three years, in 2008, cans were thrown from the terrace on to the field, and last year, as the French team did a lap of the field after winning, bottles were thrown at players.
The incident was reported widely overseas.
Mr Huddy said the bottle-throwing was extremely disappointing, and was a black mark against rugby in the South.
He agreed that most people in the South underplayed the bottle-throwing incident.
"It was really noticed by those further north.
"We had to work really hard to get another test down here, and that was no help.
"The bottle-throwing was totally unacceptable and not only did it bring shame on the city but it endangered player safety," he said.
"This year and next year is going to be massive for us, with the World Cup, and that means we have to educate people in what is and isn't acceptable.
"When in the past [there] may have been a bit of an allowance for behaviour, we'll be looking at not letting people away with it."
This year, the New Zealand Rugby Union would be carrying out full audits of all the grounds which had been selected to host World Cup matches, so the pressure was on to get things right.
He said more security guards would be employed but it was more about education and people not accepting the poor behaviour of others.
He conceded night rugby did not help the situation, with many people arriving at the ground intoxicated.
"The problem we have is people may be too intoxicated to get into the ground, but what do we do then? They might try to get in another gate or cause a commotion outside."
He said an alcohol ban was contemplated and there had been a suggestion of an alcohol-free terrace.
But he felt people should be able to enjoy a beer at the ground.
"We don't want a small cluster of people spoiling the enjoyment of others who want to go along to the rugby and have a beer when they watch the game.
"But if someone is caught committing an offence at Carisbrook, this person could be banned from the ground for up to two years."
Senior Sergeant Phil McDouall said police fully supported the zero tolerance stance, saying trespass orders would be issued to those who offend at the ground.
