The national UFB roll-out is happening in stages and all cities and towns were part of UFB phase 1 which completed in 2019. Phase 2 is rolling out fibre to a lot more smaller communities by the end of 2022, at which time about 87% of New Zealanders should have fibre available in their street. Once fibre is installed in your street it is then available for installation to your home.
Check if you can already access fibre or when your area is due to get fibre, using this broadband availability address checker.
If fibre is not available in your area there may be other services like wireless broadband which may offer improved performance over existing copper broadband. If you live in a rural area, you may be covered by the Rural Broadband Initiative (RBI).
Talk to your service provider about what options are available at your address.
