The other five family members are also being treated in Hawke's Bay Hospital.
The holiday road toll period, which finishes tomorrow [3/01] at 6am, began at 4pm on Christmas Eve.
Last year, six people died over the nine-day period - the lowest since Transport Ministry records began in 1958-59 - as far back as Ministry of Transport records go.
Assistant Commissioner Road Policing, Dave Cliff, said all seven deaths this year were avoidable.
"They all happened because of the same old mistakes being made.
"The basic messages about slowing down, not driving when you're tired, no alcohol, making sure all the vehicle occupants are safely restrained - all these things apply,'' Mr Cliff said.
The number of people killed on the nation's roads in 2013 was the lowest since 1950 at 254 fatalities. And while December's road toll of 23 was the lowest since 1965, the number of deaths still occurring on the roads showed drivers still had a lot to learn, he said.
"What these deaths keep highlighting is that the results and the gains we are making are quite fickle. There is still lots of risks out there and people need to be incredibly vigilant and careful.''
The highest Christmas holiday road toll was in 1972-73, with 37 deaths.
