After the March 15 shooting, the threat level was raised to medium from low.

Today, SIS boss Rebecca Kitteridge said it's because the attack had "given encouragement to some", and some people had found it "inspirational".

"It's more about the impact of the March 15 attacks themselves," she says.

"I think one of the terrible outcomes of the attacks is that it shows New Zealand that it makes it a possibility that we would have something like that occur."
