On the comment section of the article, someone is asking the exact same question. :)

The author answered: "I liked to shot of the tower … looks like it’s reaching out into space and time!"

None, as far as I can tell. It was probably just selected because it's a pretty picture.

I arrived in Auckland today from my home in Australia, and did a massive double-take when I opened the article. Kinda neat, considering I saw that perspective of the Sky Tower just before.

I love life's little coincidences.
