I moved from NZ where we'd done probably one of the best fiber rollouts of any country; I had 1Gbps into an apartment from about 2016 or so. Before that I'd had 200ish mbps into a house in the suburbs in about 2014 thanks to the previous tenants having run a business from the place and paid for a line in.

Now I live in the UK I can see why it's hard - too much history/housing here is just built up far too much/not built up in a modern way either. Also I think when obtaining permissions from property owners in the case of flats, Kiwis are generally more likely to approve of something like that than people here.
