Which fibre company serves your address?

Your town, and the fibre company that names it on its own page, with that company's address checker for the door itself. Every retailer here sells over all four.

No open address lookup exists for New Zealand fibre: the national map's API needs a key assigned per user and each fibre company's checker binds the person using it to that company's terms, so this matches your town to the fibre company that names it and sends you to that company's own checker.
