Months after the February 22nd earthquake in Christchurch the effects are still being felt by residents.
More than 10,000 people have sought help from Relationship Services, including many parents to deal with their traumatised children following Christchurch's quakes.
Relationship Services Whakawhanaungatanga clinical leader Pablo Godoy said each child reacted different to the quakes.
Reactions included bed wetting, soiling themselves, tantrums, disruption to sleep and eating patterns, fearing places they had never been scared off before, returning to younger behaviour and nightmares, among others.
"It's a really common reaction to stress. It doesn't mean your child is different and beyond the norm. The reason they're doing it is because they're normal. It's not the greatest way of looking at it but it's the reality of it. Children do act out, it's their way of saying something isn't right," he said.
Mr Godoy said nightmares were often a way of children trying to comprehend what had happened.
"Trying to put the jigsaw pieces together, revisiting the experience or something generic to do with the experience."
"One of the key signs to look out for is any disruption in who they are, their personality before compared to after the quakes".
