Mr O'Brien was one of those who missed out and was 8060th on the waiting list for tickets.
After entering the ballot, he changed his mind about going to the Anzac service and decided he would rather visit Chunuk Bair in August 100 years to the day after his father, John William O'Brien, was wounded there.
However, he is supporting calls for Minister of Veterans' Affairs Michael Woodhouse to review the criteria for the children of Gallipoli veterans.
Mr Woodhouse told the Bay of Plenty Times he sympathised with Mr O'Brien and the other 90 per cent of applicants who missed out on the ballot. He said the decision about how to allocate passes was made after public consultation.
"While 90 per cent of all applicants who entered the ballot missed out, a third of all children of Gallipoli veterans entered in the ballot were successful. I also want to stress that age or fitness has never been a factor in the ballot process," he said. "Government is planning a second ceremony in Gallipoli to mark the 100th anniversary of the Battle of Chunuk Bair in August 2015. This will be another opportunity for anyone who missed out to take part in centenary commemorations."
Despite his decision not to go, Mr O'Brien contacted the Bay of Plenty Times to voice his concern about the process and said others he knew in the same position were "devastated" they would not be able to go to honour the sacrifice made by their parents.
"All those that are fit to go and wanted to go should have been able to. I honestly thought they had a place reserved for me," he said. "I feel for them. If I had have had my heart set on going, I'd have been very disappointed as well."
