Air NZ, which has channelled much of its advertising energy into celebrity-studded viral videos, made the top 10 for the third year running.
Google New Zealand spokesman Johnny Luu said the results showed Kiwi creators were taking to YouTube with much success, and their inclusion in the top 10 list showed that local content creators could hold their own on a global stage.
The New Zealand Transport Agency could claim it commissioned the most popular public service video in the country, after its "Legend" drunk-driving clip became the eighth most-watched video in 2011.
YouTube trends manager Kevin Allocca said the videos showed "that around the world, whatever language we speak, there are certain things that bring us all together around a computer screen or mobile phone - adorable babies, talented performers and clever advertising."
California-based Google also published a list of the music videos that attracted the most attention in New Zealand in 2011.
American group LMFAO's Party Rock Anthem, which has been watched an astounding 324.5 million times around the world, was the most popular YouTube clip uploaded by a major record label.
The only New Zealander to feature on the list was Kimbra, whose cameo performance on Australian artist Gotye's single Somebody That I Used to Know, has been seen 24.1 million times.
Google-owned YouTube this year had 48 hours-worth of video content uploaded to the website every minute.
