Mackenzie often gets questions by parents about her age and when they don't believe her, they ask her what year she was born.
At nine years old, Mackenzie is 5'2 (160cm). That's a full 20cm taller than the average nine-year-old Kiwi girl.
It's not just pretty tall – it's almost off the charts.
Her parents are both over 6' (183cm) tall so she was always going to stand out.
Being tall isn't the end of the world but Mackenzie is mad keen on sports and that's where the problems begin.
