I remember when kogan first launched in NZ saying about the better prices that they would bring. Hasn't really been that great so far in my opinion. They haven't brought in the big items (TV's etc) to sell in the NZ market. A lot of their cameras are sourced from Hong Kong so having a $400 duty / customs limit vs $1000 in Australia really works against them. Signing up for their NZ site, they send me emails that are only relevant in Australia. 

So, in NZ, I haven't been too impressed with what they have achieved so far. Not sure if the buying of the database will push them into providing more coverage in NZ, or, if they are still going to concentrate on Australia.
