[nznog] Crimes Amendment Act #6

Does any one know where I can get a copy of the Crimes Amendment Act #6 I need to know what the story is about sending bulk e-mail from the server as I have a client wanting to do so however need to know how they can legally do it. (ie by placing opt out at the bottom is that sufficient) also is e-mail covered under this act as an offence. Thanks in advance.
