The law is almost never enforced and where it is it's the girls that suffer not you. Blow and fuck is always with a condom. These parlours are almost always well run, clean and safe with some very good looking women who are extremely skilled at what they do. Like anywhere treat the lady with respect and you can be assured of a very pleasurable visit. I use these places about once every month and the girls are nearly always very pleasant and prepared to give you your money's worth.
Most places have a large variety of types of figure and race so shop around and enjoy.
CJ's, Mayfair and Ceasars. I tried the last two. Ceasars was the lower end of the market. An old imposing building on the waterfront, the usual NZ system of an upfront 'entry fee' was in operation. This covered a massage with the lady of your choice, and I left the credit card voucher open for other services to be added on later.
