New Zealand English is just like how you and I talk, but with a few special words and ways of saying things. That's because New Zealand is a country way far away from many other places in the world, so the people who live there have made their own way of talking.
When you hear people from New Zealand talk, you might notice that they sometimes use shorter words or different ways of saying things. For example, instead of saying "I am going to the store," they might say "I'm off to the shops." That sounds a bit different, right?
They also have special words that you might not have heard before. For example, they might call a friend "mate" instead of "friend." They also use the word "kiwi" to mean both a type of bird and a way to describe people from New Zealand.
Overall, New Zealand English is just like any other way of talking - it's unique and special to the people who use it. So if you ever visit New Zealand or meet someone from there, you might hear some words and phrases that you haven't heard before, but that's just part of the fun of exploring new places!
