Street artists are calling for clearer rules around their craft, after one prominent artist was charged.

Wellington Central MP Tamatha Paul has voiced support for prolific graffiti artist Karl Truell - aka 'Pork' - after he was fined in Auckland.

Auckland street artist Jesse Jensen says there's no spaces for people to paint legally - and changes need to be made.

"There just isn't an outlet, it's like how skating used to be - now you've got skate parks. Well, where's the art parks?"
