Napier City Council are calling for legislative action to stop pitch invaders at sporting events.

Warriors CEO Cameron George warns Napier may lose out on future NRL games after 12 pitch invaders ran onto the field during the final 10 minutes of Saturday's Warriors- Broncos match.

Napier City Council events manager Kevin Murphy says something has to be done about pitch invaders to make them less brazen about disrupting games.

"How can we stop them? At the moment, they get a trespass notice and it's not really doing anything, is it?"
