Memorial services were held in three parts of the world today to commemorate two Air New Zealand tragedies separated by 29 years.

Services were conducted in Auckland and Christchurch to remember the 30th anniversary of the Mt Erebus disaster in Antarctica and the loss a year ago of an aircraft off the south of France.

The Erebus tragedy, in which all 257 people on board a DC10 sightseeing flight from Auckland perished, was also marked at Scott Base.

A service at the base was scheduled to be followed by a ceremony at the base's flagpole at 12.50pm, the moment when Flight TE901 slammed into the foothills of the mountain.

The ceremony - involving a prayer, a period of silence and the laying of a wreath of roses - was being attended by six people who lost relatives in the crash.

The six - among them Pip Collins, daughter of the pilot, Captain Jim Collins - were drawn by ballot to fly on a US Air Force C10 cargo plane for the event.

They took with them a koru-shaped capsule containing messages from families and water from Aoraki-Mt Cook.

The water, gifted by Ngai Tahu, represents both the tears of a nation and the hope of a new beginning.

Yesterday, they flew over the crash site, but could not land because of high winds and will try again on Monday.

Earlier today, a ceremony was held in France to commemorate the first anniversary of the crash of an Air NZ Airbus.

The A320, which had been leased to German company XL Airways, was undergoing trials before being handed back to Air NZ.

During the flight, it plunged into the sea, claiming the lives of the five New Zealanders and two Germans on board.

About 20 relatives of the New Zealanders travelled to France for the commemoration.

At 3am (NZ time), they, colleagues of the men and officials from the city of Perpignan, attended the unveiling a greenstone plaque on the seawall at Canet-en-Rousillon.

They then travelled by naval vessel to the accident site, where wreaths were laid on the water for each of the seven men.

At 4.46am, the exact time of the crash, the boat's horn sounded seven times.
