Dubai's main tourist attraction, the world's tallest building at 830 metres, has a New Zealand connection.

Kiwi Christopher Mills was a project manager on the towering Burj Khalifa structure, which costs $150 to take the lift to the viewing platform on the 148th floor.

Mills says it doesn't stop there.

"So above 148 there are offices and it stops at the private office at 157 and there's a prayer room at 160, and above 160 there are about 30 floors of spire."

It was opened five years ago and Mills says he was privileged to work on the project, which took six years to complete.

"If you build amazing, world-best projects you'll attract the best people in the world to come and build them.

"It attracted us, it attracted a lot of my partners and my friends - and we all came to build their dreams."
