Auckland, New Zealand and Sydney, Australia were the first major cities in the world to usher in the New Year.
The celebrations began with a fireworks display atop the Auckland Sky Tower in the city centre.
The pyrotechnics fired from two levels of the 328-metre Sky Tower, which is said to be the tallest structure in the southern hemisphere.
According to local media, there was concern that bad weather would hamper the fireworks, but it cleared in time for the display.
Sydney exploded in colour as fireworks were launched from seven skyscrapers, with seven tonnes of pyrotechnics fired from seven barges on the harbour. There was also 60 tonnes of lighting and pyrotechnics on the Sydney Harbour Bridge. The theme of the celebration was “embrace.”
Local media estimated there was a flotilla of around 3,000 boats on the harbour to watch the event.
Singer Kylie Minogue, who was designated creative ambassador for the fireworks, had a big input into the soundtrack that accompanied the pyrotechnic show.
They said 11,000 shells were fired, which cost US$6.8 million.
The City of Sydney local government predicted that 1.5 million Sydneysiders would see the fireworks around the harbour, with over a billion people watching it on TV or on the Internet.
