As as been mentioned many times New Zealand is a 1st world country (good healthcare, level of living) with a smallish population and is in the middle of nowhere.

So it could successfully lockdown for a short period, eliminate local infections and close off new entries. Most of the rest of the world has higher population densities and land borders or close marine borders that are breached.

We would have to arrange something with Eire to combined close our borders, sink incoming illegal boats or just tow them back to the mainland, somehow let food in without infections also getting in and so on. It would likely need to be longer than NZ had to get rid of local infections and we would have to stop rich city dwellers moving out to second homes and other movements within the country. It's not that it couldn't be done but it would be far harder and longer and may not be successful if once we stop it we reopen borders again.
