NZ didn't allow registration of raw .nz domains until 2014 so anything registered before that was a .co.nz or similar. It's still more common than .nz due to inertia / muscle memory I guess. I get weird looks when I give people my (name).nz email address - usually people ask if I meant .co.nZ

My suspicion is that it was due to abuse; a long time ago, I noticed some university had registered IIRC .co.br (our correct equivalent to the .com gTLD is .com.br; this is a notable exception to the assertion above that "I rarely find a reputable business that is using anything but .com or .co.XX as the primary domain", since plenty of reputable businesses use .com.br as their primary domain, not .co.br which doesn't exist).
