"While I was back in Auckland city, I randomly picked up a Chinese newspaper to read. I was surprised to see a full page of advertisement that is completely related to prostitute business," the complaint stated.
The complainant, who was born in Taiwan but moved to Christchurch aged 10, linked the sex potion ads to rapes and murders, referring to several brutal incidents in Taiwan.
They pointed to a case in which a man mutilated his girlfriend's face because she was trying to break up with him.
"The common ground of these cases is that the person commits the crime because they became extremely obsessed with something and the lack of the strength to resist their obsession.
"The ad in the newspaper is strongly contributing to these factors in a very bad way. I believe that these advertisements if is not banned, at least [they] should be managed."
The authority said the paper's managing director had suitably amended the advertisements on behalf of the advertiser.
"When I did the translation, I had a chance to study the advertisements in detail," the Mandarin Pages managing director told the Authority.
"I did have concern about the product 'Spanish Water' and my colleague rang the shop and told them that we would take the product off their advertisement, and the product was taken off the advertisement promptly on the day I did the translation."
The latest ad for Gigi in the paper mentioned products including hand-cuffs, a foot chain, leather belt, low heat candle and anal pearls but did not mention the water product.
"In light of the self-regulatory action taken by the media to amend the advertisements, the complaints board ruled the matter was settled," the authority said.
The authority's complaints board said advertisers were entitled to promote adult products, sex toys and lingerie but must do so in a socially responsible manner.
