TV3 NZ has some video of the A/C looking lonely where it stopped.

A passenger on board flight NZ2270 from the South Island town of Blenheim to Christchurch was arrested on arrival at the airport, Air New Zealand said in an e-mailed statement. None of the seven passengers were injured in the ``incident'' and the plane landed safely, the airline said.
The perpetrator is a woman, New Zealand Defense Force spokesman Zac Prendergast said. ``She claimed to have a device in her handbag so as a matter of course the defense force bomb disposal squad was called out,'' he said in an interview. ``I heard someone in the crew or pilot has been stabbed, I don't know what with or anything like that.''
The pilot and woman have been taken to hospital, the New Zealand Herald reported, citing an unidentified person at Christchurch airport. The gateway's spokeswoman Chelsea Halliwell did not return calls to her mobile telephone."

"Police say a May Day call was received at around 7:40am via the NZ Rescue Co-ordination Centre.
The pilots on board said a female passenger had attacked them and inflicted minor injuries before she was removed from the cockpit.
The passenger also made threats of a bomb being on board.
Police say the plane continued on to Christchurch Airport without further incident and landed safely just after 8am.
The Civil Aviation Authority says there were nine people on the plane but none were hurt. The CAA is not confirming whether the pilots were injured but there are reports one was stabbed.
Footage obtained by ONE News shows a male pilot with a bandage on his right arm being wheeled away by emergency staff at the airport.
The airport is in lockdown mode and the terminal has been evacuated. All flights both in and out of the airport are currently on hold and passengers heading there should expect delays.
Emergency services are at the scene and Christchurch police have taken a woman into custody.
The plane is a Jetstream 32 - a twin engine aircraft that reportedly has no cockpit door between the pilots and the passengers."
