In the major cities you can get unlimited fiber with 100Mbit/s connection for around $90 NZD a month.

in more rural area's the internet tends to be standard ADSL.

(side note; the governments "fiber to the door" roll out is apparently 68% complete for urban areas as of June this year).

I pay around 80nzd/mo for unlimited . Latency is not awesome. That was literally the only thing I was worried about moving back to NZ "how well will Netflix work and will managing servers drive me nuts". Netflix is still awesome, the round trip to US based servers is noticeable - 130ms west coast. That said I get home from work in the largest city and go for a swim in beautiful bay 2 mins walk from my door ...
