"It's tragic circumstances for the entire community and our thoughts are completely with the family and friends of the little ones involved, and also the rest of the community of Wellington," she said.

"All of our officers will be taken care of and certainly it's one of those jobs where you sometimes wish your arms were a little bit longer so you can wrap them around all your staff," she said.

"We have liaison officers in contact with the family, obviously they're grief-stricken in relation to the tragedy and the loss of their children and we will be offering our assistance to them as well.
"We would be encouraging anybody who is feeling traumatised as a result of the incident to get in contact with their GP and seek medical help."
