Semb was working in Australia and made regular trips home to see family in Kerikeri. He was expected to move back permanently at the end of the year.
Finlay-Semb was just 14 when her father was killed at Erebus. He was a crew member on Air New Zealand flight TE901 when it crashed into the the Antarctic mountainside in November 1979, killing all 257 on board.
Finlay-Semb said she had struggled for years after Erebus and had been through all sorts of emotions. She hadn't fully come to terms with losing her dad and now had to cope with her husband's sudden death.
The couple had children together and were grandparents.
"I have been able to understand what our children are going through because I have experienced that same loss," Finlay-Semb said.
"Chris was really supportive and helped me deal with the loss of my dad a lot. He was rapt when I got to go to Antarctica [on a memorial flight in 2011]."
Semb's body was expected home soon.
Rebecca Flood described her dad as "an amazing father and grandfather" who "was very talented and could fix anything".
"My children Ben, 3, and Madison, 6, loved being around him and he loved being with them. We just want to get him home."
