A new study will look at how playing could help children deal with trauma from the Canterbury earthquakes.
University of Canterbury health sciences researcher Junita Nawawi said acting out experiences through play could help children make sense of what they've been through.
"A child who may had experienced shakes would perhaps re-enact that experience, so if they had a dolls house they might shake the doll house, or use the sand in the sand pit to make liquefaction around their neighbourhood."
Ms Nawawi, who is a trained counsellor, would be present during the therapy should the children also want to talk through their experiences.
"It's a therapeutic relationship similar to that of a counsellor for an adult, but in this case the child will communicate with me through their play."
