Possibly not, but if there are no NZ business to pay taxes, then either we have to borrow more as a country or slash services. :
I don't think tech retailers are big either way with the economy - I'm still going to shop for groceries locally!
I do find it quite interesting when I was on Australia, how much people over there are all for supporting aussie owned companies. I believe it is similar is the US. But in NZ we don't seem to care so much, and it comes down to price.
I lived in Oz and found it utterly bizarre - to the point that they will buy rice grown in the Murray Basin which has a serious water supply problem over that grown in INdonesia. Frankly a lot of was straight racism as far as I could tell - it's one the things I don't like about OZ
If you are buying from amazon, then there is no CGA protection. The extra you pay for GST is sort of like buying an extended warranty.
Amazon cares about their customer service - they are known to have superb customer service. Dick Smith and Harvey Norman are both covered by the CGA and both are regularly on Fair Go for flouting it. It's not the GST I'm talking about here BTW - I'm talking about some electronics (not Apple) and software which is almost double in NZ compared to the US - that's called profiteering - it's more he distributors than the retailers - but of course the retailers and the govern are happy to go with the bigger margins.
