I'm from nz as well, I wouldn't get your hopes up for 5g. We have too many trees for 5g, its only really planned in malls, airports, universities ect. Large indoor areas.
I think the bigger issue is oligopoly of cell providers. Puzzler how (reasonably) well Chorus operates, yet cell providers has big money to shelve for licences which is hard for polichickens to say no to.
The new 5G plans are pretty much same as 4G - it's not realistic alternative for broadband. Meanwhile in most Eastern European countries you can get truly unlimited data plan for less than $100 (we've got one for a 100 boat + 8 cameras marina).
