The first European explorers to discover New Zealand were dutch, so they named it after the province in the Netherlands called Zeeland.

Scrape away the paint and you'll find it

Old Zealand is in the Netherlands, although it is spelled Zeeland now instead of Zealand. It was a Netherlander, Tasman, who discovered New Zealand, so he named it after a part of his own country.

The name means "Sea Land".

There's also a Zealand in Denmark but this is not the one that New Zealand is named after.

Denmark. When the dutch people settled here, they called it Zealand.
