Revellers across the globe are gathering to welcome in the new year, with New Zealand and Australia leading the celebrations.
A giant clock in Auckland's Sky Tower counted down the minutes until midnight (11:00 GMT), when fireworks erupted.
Up to 1.5m people have lined the shores of Sydney harbour in preparation for the city's famous firework display.
Celebration plans have been muted in Indonesia, however, in the wake of the AirAsia Flight QZ8501 crash.
