"This is a tragic loss of life at Christmas time. I cannot reiterate enough to everyone not to use mobile phones while driving."
Road conditions were treacherous at the time of the crash because of extremely heavy rain in the area.
The three women, a 24-year-old and her 19-year-old sister, from Tokoroa, and a 20-year-old friend originally from the south Waikato town and now living in Norsewood, had to be cut from their extensively damaged car by the Fire Service and were taken to Waikato Hospital with serious but non life-threatening injuries.
The teenager yesterday had surgery and she was last night recovering in a ward with the two older girls whose conditions were stable.
Waikato Hospital spokeswoman Mary Anne Gill said none of the girls would be going home for Christmas but they were all in a room together.
She said one of the women cried when she heard the news of Ms Jessep's death.
Mr Troy said the crash was a tragic reminder that motorists needed to be aware of the dangers of being distracted while driving.
"Because of one moment of inattention Christmas for a number of families will not be an enjoyable occasion."
Ms Jessep had worked as a St John regional community care manager for the Midland region until November this year when she resigned.
A St John spokeswoman said members were saddened to hear of Ms Jessep's tragic death and her family was in their thoughts.
The use of hand-held mobile phones while driving was outlawed in November 2009, but a survey last year found one in 12 drivers, or 22 per cent of motorists, still sent texts while driving.
