An ANZ Air New Zealand Boeing 777-300, registration ZK-OKQ performing flight NZ-5 (dep Aug 17th) from Los Angeles,CA (USA) to Auckland (New Zealand), was enroute at FL340 over the Pacific Ocean about 3 hours prior to estimated arrival into Auckland, when the crew decided to descend the aircraft to FL270 due to forecast turbulence ahead. During the descent the passenger oxygen masks automatically released and an automatic emergency announcement regarding loss of cabin pressure occurred. The aircraft later climbed back to FL290 and again descended to FL180 while continuing towards Auckland. The aircraft landed safely on Auckland's runway 05R about 3:20 hours after leaving FL340.

The airline reported passenger oxygen masks automatically released while the crew was descending the aircraft from FL340 to FL270 to avoid forecast turbulence, an automated warning sounded prompting passengers to put on their oxygen masks. This however was not an emergency situation and the masks were not required.
