many legally charge what they call 'shift fees', and most require their workers to buy their own clothes and accessories. This means that on a slow night the worker may actually lose money. However, brothels and escort agencies are generally seen as preferable to street prostitution, as their environment appears to be relatively safe. Brothels vary in size between 3 sex workers on duty to up to approximately 30. Brothels and agencies advertise through a range of media, including billboards, the Internet, and late night television advertisements, but especially newspaper advertisements, particularly in New Zealand Truth until its closure in 2013. One of the results of the law change is that 16- and 17-year-old sex workers are no longer allowed to work in brothels. With the exception of several well publicised cases this change has been successful. Sex workers who do not wish to be employed often set up one-person or two-person brothels or agencies, commonly in their homes. Within the definitions of the act these are called small owner operated brothels (SOOBs). They tend to rely on classified newspaper advertisements (particularly New Zealand Truth until its closure in 2013), or by advertising on the Internet. The location of brothels within local territories has been a continuing area of litigation, and a poll conducted in March 2011 suggested that 66% of the population would support a ban on brothels in residential areas. The same poll showed a 50% support for banning street prostitution. This poll published by NZ Herald was initially commissioned by political Christian group Family First and run by Curia Market Research. The research has drawn criticism as potentially representing bias due to the ties to Family First. Potential areas of result skew include: An unusually high proportion of respondents from more conservative rural areas. 31% of respondents versus 8.4% population distribution. (Source: see table one) Age distributions not reflective of the general population instead favoring older more conservative age groups (although the overall effect of this is unknown as approval and disapproval varied significantly throughout age groups without clear trend towards changing attitudes with age). Respondents were 57% female and only 43% male while population distributions show females as 51% of the population. This may have had significant effect as females were found to be more substantially more likely to disapprove of prostitution (For females 44% to 64% approve regulation, while in males only 28% to 39%
