I'm looking to buy an iPhone XS while I'm out of country (Canada), as it works out much cheaper.
The only issue is, I see the Canada model lacks LTE band 28 which appears to be in use by Spark and Vodafone. Is this a major issue?
2degrees use Band 28 also. The phone would work on 3G ok in NZ but you will find 4G coverage more limited to metro areas.
If you have a look at https://gis.geek.nz it will have a map of all NZ towers and you can see which frequencies are used at each site to give you an idea.
Little bit gutted by this. Last year's iphone X has band 28. It would have been nice to save >$300 by getting one here. Now gonna have to wait till I get back, as Apple obviously won't deliver from NZ to Canada :-)
