Families of those killed in New Zealand's greatest peace-time disaster will meet the Prime Minister and Governor General in Auckland today.
A private ceremony is being held at Government House to mark 40 years since the crash of Air New Zealand Flight TE901 on Mt Erebus in Antarctica in 1979, with the loss of 257 lives.
Reverend Richard Waugh will take part in the service and speaks to Susie Ferguson.
Other commemorations today include a ceremony at Scott Base in Antarctica.
At 12:49pm, staff will gather at a Koru memorial on the hill above the base for a short reading, a message from Prime Minister Jacinda Adern, and a moment's silence.
Back in Auckland, there will be a service and wreath laying at the Erebus Crew Memorial garden at Auckland Airport.
The Erebus crash killed all on board, including 20 crew members.
