from Customs website
"
Customs will not collect GST, duty or charge an Import Entry Transaction Fee (IETF) on goods valued $1000 or less, unless the goods are part of a large consignment.
This does not apply to tobacco and alcohol products - duty and GST are collected regardless of the value.
If you buy goods valued over $1000, you'll have to pay duty and GST plus the IETF and MPI levy when the goods arrive in NZ.
This calculation is an estimation only and applies to goods imported for personal use after 1 December 2019."

I bought my bow from eBay, which is collecting GST, so as my bow was < $1,000 I had only to pay the GST.
A quick research I did, was that if I'd bought a $1,500 bow, from 'wherever', it would have attracted duty of about $75 on top of what ever the GST was. And then you've got to deal with Customs etc when it gets here, to pay the moneys.
Easier to get a cheaper bow and let eBay do the GST faffing around.
Though in retrospect, I coulda saved myself the GST money, by buying from somewhere that didn't collect GST and then keeping the total purchase+ shipping+insurance, below $1,000.
