The Civil Defence Minister says communication problems in this week's deadly Port Hills wildfires has highlighted the need for changes in the law governing emergencies.
Gerry Brownlee has been critical about the lengthy delay by Christchurch officials to declare a state of civil emergency this week.
It didn't happened until 48 hours after the fires began. By that time homes had been destroyed, scores of people evacuated and a helicopter pilot fighting the fire had been killed.
Brownlee described the situation in Christchurch as "all pretty unclear" and said he was not happy.
He said there was a need to streamline the country's civil defence laws calling for a clear, simple chain of command in times of emergency.
