If you go here: Sammobile latest firmware for SM-N986B
It shows you the different regions and the latest version of firmware they are on. I only assume it corresponds to an OTA update....not sure.
NZ is quite far down the list. I have actually given up on waiting for an update from Skinny. You can compare the version you are running with the latest shown against NZ to determine whether it's just you missing out.
I use frija to get the latest - all you need to do is indicate your model number and the region you're interested in.
I am pretty relaxed about the region - currently working perfectly on the UK firmware - had it on Germany before that.
Download the zip using Frija, unzip to a folder, then use Odin to flash.
But that's just me being impatient. One day it might bite me in the arse...but so far so good.
