Ms Casey acknowledged that in reality, if a tsunami was to hit, children would not necessarily be wearing sun hats and they did not expect police to be available to stop traffic for them.
"They are aware this is just pretend.
"It's about making sure the children know what to do in an emergency. We are trying to get our community aware so everybody's aware. It might not happen in school time. We really want it so whatever happens, every child knows what to do, how to look after themselves and what's the best thing to do in that situation."
The school also asks families of children to bring a bottle of water and can of food in case a disaster hit.
Western Bay of Plenty head of road police acting Senior Sergeant Wayne Hunter said he was concerned that stopping of traffic would create a large back up but things ran smoothly with little delay.
"I'm quite glad at how well it went. It's a bit of a wake up call actually. It got me thinking, if something did happen involving schools."
