TLDR - be careful of the ChargeAmps brand.
Full reply: If by the 'Swedish' ones you mean ChargeAmps, be mindful that a number of NZ Leaf owners, including me, have had problems with these.
The dealer I purchased off reported he'd had to return many of these; he believed it was a problem associated with the changes made to the product once in NZ (not sure what more the importer does other than replace the plug?).
We had the ChargeAmps Ray that, when combined with the suitable external adapter thing, enabled us to charge at both 16A from the caravan socket on the wall of our house, or at 8A from a three-pin plug. After about six months it became increasingly temperamental to the point it wouldn't charge the car.
The dealer wasn't willing to provide a new Ray, based on his history with the model, but did send me two separate cables to cover 8A standard and 16A caravan charging. The 16A one was the OEM Audio model - I recall talking to the guy from the firm (Paul?) at the time, and he said he had plans to have the factory produce a model in which amperage could be altered (like the Ray) - but perhaps nothing ever came of that? (I was supposed to swap out these two cables for one of the new models.)
