Prime Minister John Key says he can't rule out a "home grown" terrorist attack in New Zealand but believes the risk is lower than in many other countries.
Mr Key was speaking today following last week's killings in the United States by two US citizens.
He was asked at his post-cabinet press conference whether he had concerns about a "home grown" attack in New Zealand.
"I can't rule that out simply because I don't think any country can," he said.
"But as I've said in the past, while we're not immune from risk I genuinely believe we are at a lower risk than a lot of other places in the world."
Mr Key says its known that some of the 40 people on the SIS watchlist could "potentially undertake a domestic terror action" but the SIS and the GCSB are highly effective agencies.
"The concerns are always about `dark communications', those that the agencies can't access, or people we simply don't pick up on the radar screens," he said.
