They're vans that have sparked hundreds of awkward conversations on family holidays.
Now a Mangawhai man who helped kick off the campaign to bring an offensive campervan company to justice is thrilled the cause is gaining government attention, and possible intervention.
Terry Harris contacted Whangarei MP Shane Reti in January after he saw a campervan from Australian firm Wicked Campers bearing an obscene message that was deemed too offensive to print in this newspaper.
Several ministers - Paula Bennett, Louise Upston and Maggie Barry - had since taken up the cause and are trying to find ways to get rid of the slogans, which had sparked a string of complaints to the Advertising Standards Authority. The company has ignored the rulings.
Despite the media attention over a number of years, the company was yet to receive its first fine and the government was now scrambling for options, which could include banning Wicked Campers' vans from public camping grounds, referring the company to the chief censor or using park rangers to fine people driving them.
