Xarien was born on the side of Auckland's Southern Motorway in July. Curtis went into labour five days before her due date and was on her way from her home in Otahuhu to Auckland City Hospital to meet her midwife and Roi when Xarien decided he couldn't wait any longer to make his entrance into the world.
Diprose met the new family about two weeks after Xarien's birth.
"It was cool to meet him, I couldn't remember his face from the birth," Curtis said.
"I was a little bit nervous but it was really cool."
She headed out of Auckland for Christmas and was planning three celebration meals with family, all thrilled to share their day with the "motorway baby".
As for 2016, if Curtis and Roi welcome any more children it's likely to be a calmer affair.
"Hopefully the next one will be born in the hospital," she laughed.
After the birth, North Shore-based Diprose was praised by Police Commissioner Mike Bush for his efforts.
"This was a highly stressful incident that posed a very real risk of harm to mother and child. Errol's ability to step up and take control is a great example of the skill and professionalism of our staff under pressure," Bush said.
