including Mr Choudhary, to change their votes at the last minute. The Act replaced the previous legislation, including repealing the Massage Parlours Act, largely removing voluntary adult (age 18 and over) prostitution from the criminal law and replacing it with civil law at both national and local level. A distinction was made between voluntary and involuntary prostitution. It remains a crime to coerce someone to provide sexual services. Sex work is also prohibited for those on temporary visas, and immigration for and investment in sex work is prohibited. Contracts between provider and client were recognised, and providers have the right to refuse services. Contested contracts can be referred to the Disputes Tribunal. Advertising is banned, with the exception of print media, which is restricted. The Summary Offences Act remains in force in relation to soliciting, which may be classed as offensive behaviour. The Criminal Records (Clean Slate) Act 2004 also allows sex workers to apply for previous convictions to be removed from the record. Sex work is recognised (but not promoted) as legitimate work by Work and Income New Zealand, who may not advertise vacancies in brothels or suggest people start sex work as a means of getting off a benefit. Now, workplace safety and health rules, developed in consultation with the prostitutes' collective, apply to sex work. Employment disputes can be referred to the Labour Inspectorate and Mediation Service. There is an obligation on employers and employees to practise and promote safe sexual practices. The Ministry of Health has the responsibility for enforcement. Registration of indoor sex workers with the police was replaced by certification at an administrative law level of brothel operators. Prior records have been destroyed. Refusal of a certificate is permitted for prior criminal offences (not necessarily related to prostitution). Police activities changed from the registration and prosecution of sex workers to protection. The Police Manual of Best Practice was amended to include prostitution. Local government was empowered to develop by-laws for zoning and advertising, but not prohibit sex work. In summary, the Act decriminalised soliciting, living off the proceeds of someone else's prostitution, and brothel-keeping. Following passage of the Act, the Maxim Institute and other conservative Christian organisations tried to gain an appropriate number of signatures for a citizens-initiated referendum under the Citizens Initiated Referendum Act 1993. The initiative was sponsored by two United Future MPs, Gordon Copeland, the bill's most outspoken critic, and Larry
