Hi,
Following up on my earlier response, I had a brief informal discussion with our local Police Arms Officer, who gave the following general advice:
- if you import or carry a normal sporting/utility/pocket knife "for
good reason" there should not be any problem - note: being a collector,is not in itself a good reason.
- don't import or carry any "provocative" knives - ie, those knives
specifically designed for attack, fighting, combat, concealment, or that have an automatic action.
- it seems that in general, it is OK to import "folding pocket
knives with a blade less that 10 cm" (other than when they are those
types mentioned above?). This 10 cm limit only seems to apply to importing a knife, and not to carrying one?
- you may be asked on to entry to NZ, to undertake that you will
take the knife out again. The intent of this is allow short-term visitors to bring in a dubious knife, as long as they don't dispose of it NZ.
- it is possible to get pre-approval from the Police to import knives that would not otherwise be allowed in, but the process for that can take time. As a collector, I have obtained such approval in the past.
As in the US, NZ law can be vague and grey in this area, and the Police have a wide range of interpretation and discretion, which can be in your favour, but may not be. If in doubt, be conservative!
Good luck, and have a good time in NZ.
Siggy
