Hi
We used AA Property Checks in Chch for both our purchases - I have one of our reports here somewhere if you'd like to see it - it can be emailed.
We found them to be very thorough and fair with their observations and, at around $400, good value. They were also able to get out to properties quickly and on time (definitely a bonus when you're sending them round to someones house to crawl all over it!). The reports, whilst not always demanded by mortgage co.s, certainly put our minds at rest at "what lies beneath", especially as we weren't entirely sure what to look for in NZ properties.
Email/PM me if you would like a copy of the report.
Regards
Moorf
