More than 100 family members of those who lost their lives in the Erebus tragedy will travel to Antarctica on a remembrance flight next week.
The Government announced last year that up to 80 family members who lost relatives in the 1979 disaster would be flown to Scott Base.
But after consultation with the United States Antarctic Program, that number has grown to 104.
Family members will spend five hours on the ground at Scott Base and take part in a memorial service conducted by the Dean Of Christchurch, the Very Reverend Peter Beck.
Representatives of six families were chosen by ballot in 2009 to travel to Antarctica for the 30th anniversary of the disaster, in which 257 people died after an Air New Zealand plane flew into Mt Erebus.
The latest flight leaves next Wednesday from Christchurch, weather permitting.
