While his time at the wicket was limited to a few indoor sessions, his four children had all played and son Conor had represented Auckland in age group levels.
Kelly was originally going to take his wife, Marie, but she couldn't get time off work so she passed the honour on to Conor, the only child who could make it.
Since he was named the winner of the trip, Kelly said he had messages of congratulations from all over New Zealand, Ireland and England.
Kelly's daughter is living in London and the pair met her yesterday.
"We were sitting outside and heard a heap of Kiwis going by and they were from all over New Zealand," he said.
"We just started talking and about the World Cup and I showed them the tickets and they said, 'You're joking' - they knew about me, it's crazy."
Asked how he rated the chances of New Zealand winning the final, Kelly said the men in black could surprise the cricketing world once more.
"England is a very good side but you never know on the day. I think we've got a very good chance of doing it, I honestly believe that."
