Bottom line: This insert woodburner produced 7.5 kW when NES tested. It has a predominantly convective heating mode and is NES (clean-air) approved for urban areas. It has OK emissions performance (though slightly below average for a NES compliant woodburner) and OK efficiency (though slightly below average for a NES compliant woodburner).

Testing for emissions, efficiency and power output using AS/NZS 4012/4013 was carried out by an independent lab in New Zealand.
We analyse data from National Environmental Standards (NES) testing to generate scores out of 10 for emissions and efficiency, along with an overall score. This gives us a clear picture of the performance, features and specifications for almost every model on the market.
Where available, we've also included the NZHHA output results. These results reflect the absolute maximum heat output you could achieve in your home.
Price is from the manufacturers’ survey and is without a flue kit unless stated otherwise.

Regulations regarding emissions in Christchurch forced us to bin our old Masport free standing log burner, which didn't emit any smoke when burning dry wood and which kept the whole house warm, and install a new efficient stove which theoretically throws out the same amount of heat. Well, it may do (how can I measure it?) but it doesn't heat up the house the way the old Masport did.
Maybe, it depends on what you're after.
