This year's toll rose to 19 when Tongan woman Leotisia Malakai, 55, died in hospital on Sunday following a bus crash on Christmas Eve in Gisborne.
Malakai was among a group from Mailefihi Siu'ilikutapu College who were in the country with their brass band to help raise funds for their school.
Two others - Talita Moimoi Fifita, 33, and 11-year-old student Sione Taumalolo - were also killed in the crash.
The youngest victim this year was 2-year-old Tyler Te Ruru Ahurei Davis, who died in a driveway accident in Te Kauwhata on Boxing Day.
The little girl was killed on a public driveway, which meant the death is included in the official road toll.
The first fatality of this year's holiday period was 83-year-old Myung Wha Lim, who died after being struck by a car in Takapuna on December 23.
National road policing manager Steve Greally said earlier the high number of deaths was disappointing and devastating for families.
"It's horrific.
"What's meant to be a festive and family time have been completely shattered by these accidents.''
