Labour promised to fund 80 new mental health positions in Canterbury to help young people deal with quake-related post-traumatic stress disorder (PTSD).
University of Canterbury research shows up to 80 per cent of Christchurch primary schoolers developed PTSD symptoms after the region’s earthquake sequence, which started in 2010.
The study found the rate of PTSD is double that recorded for children in big earthquake disasters elsewhere in the world.
Researcher Kathleen Liberty said that was due to the "unprecedented" rate of aftershocks between 2010 and 2012, with over 100 shallow earthquakes magnitude 5 or greater.
She said for the children starting school "a great portion of their life would have been in this disaster community, which produces a chronic stress response".
Waltham Primary School principal Gordon Caddie said the quakes were challenging for children and affected their learning.
Too many children had waited for mental health help since the quakes.
"Kids are feeling less certain about their safety… [they’re] growing up hearing messages that we aren’t always safe, and that things can go wrong."
Caddie said schools had watched the election closely, as a change of government could have a big effect on education and the help children received.
Caddie said the Ministry of Education had tried to help Christchurch schools to keep up with children’s mental health needs, but he was looking forward to a "change in direction".
He said extra mental health staff would be fantastic for schools.
"Any help is appreciated, and hopefully that’ll bring the waiting lists down."
