flour new zealand biograins

hi there, is there anyone out there from NZ who has experience using NZBIO GRAINS organic flour?

im comparing different oganic flour in an effort to choose a supplier for a small scale bakery im setting up.

I cant seem to get the BIOGRAINS flour to perform, with less volume, and keeping time but before i give up hope of using a local product i thought id ask:)

cheers

james
