Sounds like they value their privacy, so I wouldn't insist.
NZ is very strict and all food must undergo inspection with no guarantee of clearance.
I sent a large envelope, under 1 lb, to Australia and it cost me $25 with no tracking. It took 3 weeks to be delivered. I can't imagine the cost of shipping something that weighs more than that, plus having to pay duty or taxes on it may end up costing more than the product itself.
If saying thank you is enough for them, I'd leave it at that and pay it forward to someone else in the future.
Good luck with your decision.
