Wairoa I-Site manager Sally Simpson said there had been "absolute disgust" from the community at the robbery of the visitor.
"I hadn't heard of one forever so it was really surprising. It definitely is not [a common occurrence] ... It's a safe town," she said.
"We're all thoroughly fed up with the negative messages that go out about Wairoa instead of positive message of how life is every day for us."
Wairoa Police Senior Sergeant Tony Bates said though it was not common for young children to engage in such behaviour, it did happen. "There are children who wear various colours that maybe are younger than that, but this is not a common occurrence" he said.
Steps were being taken by people in the town to combat a range of social issues.
"There is a foundation group looking at community safety," he said. "It is a cohesive group encompassing a lot more people to look at all issues that relate to community safety be it health, crime or whatever."
