Mr Ashton may not want to accept it but it was his own actions that cost him this prize and it is a telling lesson for anyone who still views drink-driving as a minor offence.
As this paper has pointed out before, people who get behind the wheel after drinking alcohol are putting not only their lives at risk but the lives of others as well..
In 2011, a third of these crimes ended in someone's death on New Zealand roads
Despite this, many people continue to view it as a petty crime.
The point has not been lost on Lion's external relations director Liz Read, who says awarding Mr Ashton the prize would have sent the wrong signal about drink-driving and the company's responsibility to discourage alcohol-related offences.
Such offences disqualify people from winning competitions run by the company on a regular basis - so regular that she has been astounded by the number of people with drink-driving convictions.
If there is anyone Mr Ashton should be angry with, it is himself.
