Second on that list was "Japan earthquake" after people hit Google for more information about one of this year's most devastating disasters.
This year, Sonny Bill Williams trumped Justin Bieber in the most popular searched images, proving biceps and ball skills could overcome Bieber fever.
Google New Zealand spokesman Johnny Luu said the global internet search engine was often the first point of call for information.
"These annual search results give us a real snapshot of the big events, memorable moments and growing trends in New Zealand this year."
Also high-up on the fastest-rising search ranking - comprised of search terms that have seen the largest increase in volume over the last year - was "Her Royal Hotness", Pippa Middleton, and the viral "nek minute" video on YouTube.
The California-based internet powerhouse also kept track of the more quirky queries typed into the search engine.
The top searches for "what is?" showed New Zealanders were most interested in learning what "love" is, with "energy", "culture", "Twitter" and "planking" filling out the top five.
Prime Minister John Key's son's contribution to the online craze of planking may well have led to the number of New Zealanders questioning the internet fad.
The top celebrity fixes were predominantly from Hollywood, with Kim Kardashian, Scarlett Johansson and Harry Potter's Emma Watson making the top three.
But Kiwis were also a patriotic bunch, with Ken Ring, Kimbra and Sonny Bill Williams making the fastest-rising people list.
Mr Luu said the year-end zeitgeist was a cultural barometer that showed "what quickened our national heartbeat and drove our curiosity".
"From news and current affairs, to pop culture, sports, cars, and everything in between, search trends reveal what's on our collective minds," he said.
