A midwife made a frantic dash to deliver a baby in a car parked on the side of the road.
Tracey Wiles, from the Close to Nature midwives collective, expects she'll get a speeding ticket for the mercy dash to Whenuapai, but says it will be well worth it.
"There're always speed cameras along there so there's probably a ticket coming in the mail."
Muriwai couple Tim and Wiebke Lum had planned to have their second child at North Shore Hospital but baby Luka decided to arrive early.
Wiebke went into labour about 3pm on Tuesday and told her husband to come home from his city office. The couple left Muriwai about 4.30pm but Wiebke's water broke as she was getting into the car.
