916MHz in New Zealand

Hi Clemens, It's not an area where I have expertise but spectrum usage is searchable at

The licences in that part of the spectrum seem to be for links between commercial radio studios and their transmitter sites. Clicking on the links at the left of the table will give details of the transmission.

The homepage at

has an email contact link at the bottom of the page if you want to contact the spectrum management people.

You are almost cerainly operating under the General User Radio Licence for Short Range Devices. As you note, you are permitted to use 3mW eirp over the range 915-921 MHz. That legislation is current, but it's on a shared basis, see notes 3 and 4 at

=================================================== 3. Frequency use is on a shared basis and the chief executive does not accept liability under any circumstances for any loss or damage of any kind occasioned by the unavailability of frequencies or interference to reception. 4. Should interference occur to services licensed pursuant to a radio licence or a spectrum licence, the chief executive reserves the right to require and ensure that any transmission pursuant to this general user radio licence change frequency, reduce power or cease operation. ================================================

So, If you experience interference you have to accept it, or reduce the effects by some means, maybe shifting freq, relocation, different antennas, polarisation, shielding, or if all else fails: black magic?! One thing that maybe possible is to shift to 921-929 MHz, where you are permitted to use 1000mW eirp. HTH,
