A senior cabinet minister has called for action against Wicked Campers over the "despicable" signage on its rental vans.
The Brisbane-based company has been heavily criticised for years but hasn't removed what have been described as violent, misogynist, racist and homophobic slogans.
"I can't repeat what's on those vans," Paula Bennett told Paul Henry this morning.
"You couldn't print it, so how on earth can you have it on campervans travelling around that children are seeing?"
Councils had the ability to fine people if their signage broke by-laws.
"When a van is stopped, effectively it is a sign and they can presumably be taken to court," Paul Henry said.
"Let's do it," Ms Bennett responded.
"Let's do some really strong messaging ... the best way is for people not to be hiring from them because of the risk of being fined."
In 2014 Australia's Senate called for a particular slogan to be removed.
It said: "In every princess is a little slut who wants to try it just once."
In April last year community outrage was reported in Brisbane over other slogans such as "she can't wrestle but you should see her box".
In May last year New Zealand's Advertising Standards Authority (ASA) upheld several complaints and ordered Wicked Campers to remove three offensive slogans.
One of them said: "I've often wanted to drown my troubles, but I can't get my wife to go swimming."
The ASA described Wicked Campers slogans as "deliberately provocative and offensive".
National MP Shane Reti is running a campaign in Northland to force the company to remove the slogans.
"Every constituent and every person I speak with says this is unacceptable," he said last month.
