NZ post has a system called 'You Shop'. It give me an American & UK address that I can ship items to, and they then forward to me in NZ. The entire service should take 2 weeks.
Since January though, they have increased the prices by 62%, which is also an increase on last year's increase to include 15% GST.
I purchased a poster on eBay, unframed and had it shipped this way. It was $48NZD shipping (The US sellers quoted me $12 US
) as it was weighed "volumetrically" not by actual weight.
The shipping is now taking 6 weeks, which they are blaming on Covid, but according to the reps I've spoken to on the phone, its not true.
They have recently gone through a 'rebranding' but that means that they no longer update any tracking on their websites.
Lastly, I shipped a box to the US last week. I input the dimensions, weight and it calculated the shipping, sent me the label to print and boom.
Off it went. 3 days after it reached the US, NZ post changed their mind and said that the shipping they had already charged me for was wrong, and instead of it being $42 it was
$92!
So a heads up that NZ post is being really difficult, above and beyond Covid. Having seen a giant loss last year they are now recouping that by screwing kiwis.
