Professor Ardagh has been made an Officer of the New Zealand Order of Merit for services to emergency medicine - though it is not his efforts in the chaos of February, along with numerous other tireless doctors and nurses, that brought him the honour.
As national clinical director for emergency department services and "target champion", Professor Ardagh has led the drive in recent years to improve the waiting times and efficiency of treatment of patients at emergency departments throughout the country.
He considers the honour a "great recognition of emergency medicine and emergency nursing really".
"It's a reflection of what we have achieved in those fields, and in emergency departments generally over the last couple of decades ... I think they have improved markedly.
"We are not there yet ... but we are certainly going in the right direction."
Some of that work in Christchurch in improving how the hospital operated meant it was in good shape to handle an event like the February quake, Professor Ardagh said.
"It was a momentous occasion in many respects - obviously as a city, but also in the hospital system. I think one of the things that we are all proud of is that we coped remarkably well."
