Hi @Zamasu Sama
I agree with @Nick Fazakerley that your local PIA is probably the best place to get RE info for NZ. If you want some contacts for the CHCH association to flick me a PM/colleague request and I can forward you their details if you need.
We used to be on the committee of the Otago branch for years and you get your best insight to the business talking with those locally and the fees are usually really cheap for the amount of info you can access.
I agree with @Dean Letfus that property talk is probably the only real forum type thing set up for NZ at the moment, unfortunately. I personally don't like the tall poppy rubbish that gets spouted over there so would much prefer to have something more NZ based build up over here where there is much more of a community feel for helping each other.
Try this forum thread where a number of the Kiwi's on BP have started to try to get together and help each other out https://www.biggerpockets.com/forums/86/topics/308...
Like I say sing out if you need any help?
