Low power FM broadcasting
In New Zealand you are allowed to broadcast a lower power FM radio station without paying for a licence, so long as your maximum output is 1 watt EIPR (Equivalent isotropically radiated power). There are a few other regulations surrounding this though if you are thinking of becoming a radio star!

Signals should be vertical in polarisation. Carrier stability needs to be within +/- 5khz. There are rules around designation of emissions pertaining to mono, stereo, and stereo/muitiplex data, expressed in numeric and alphabetical code (EG 180KF3EGN) each letter relates to a rule.
Compliance
It is a requirement that you, as the broadcaster, broadcast your contact details in reference to your radio station at least once in an hour, every hour.
Radio inspectors are out there, and yes, they are monitoring. Fines can be imposed to those not following the rules.
There are restrictions in certain areas, on certain frequencies in radio sensitive areas, (such as an airport)
