It was a family affair in the Lonergan household, with Lonergan's son and parents in Wellington to witness him receive his award.
Lonergan is rarely lost for words - he hosts a sports radio show - but struggled to articulate what the honour meant to him.
"It's flattering and humbling," he said. "It's not something I expected. I'm very flattered that someone even spent the time to put in a nomination for me."
Lonergan played 11 tests for the Kiwis between 1985 and 1991 but has made more of a name for himself as an event organiser and estimated he has raised close to $5 million for charities.
He's arranging 26 events over the next 18 months, including visits by former US vice president Al Gore, golfer Greg Norman, former world tennis No 1 Andre Agassi and celebrity chef Gordon Ramsay as well as the next instalment of the Fight for Life charity boxing event.
More than 130 people are receiving honours at investiture ceremonies at Government House this week.
