It’s fibre from the home to your provider. New Zealand's current international connectivity is provided by three under-sea fibre optic cables with a combined total throughput of 73 terabits per second.
I merely told it to divide 73 terabits by the population of New Zealand and to express that in megabits. So yeah no consideration of usage patterns: "nonsense numbers" just like the supposed 46G wifi this story is about.
I do agree that all these numbers are pretty meaningless . Somehow truth in advertising laws don't apply to many of these claims. Only seen the Australian regulator really crack down on it.
I guess Australia is international? So most? Depends on how much your ISP has provisioned of course. There are some very premium ones and ones that are less so. You get what you pay for as usual
