More than 100,000 people have registered for New Zealand's first nationwide earthquake drill and the Government is aiming to enrol at least a million.
It's called ShakeOut and it will take place on September 26.
"The Canterbury earthquakes have shown us that we need to be prepared and practise how to protect ourselves," Civil Defence Minister Chris Tremain says.
"ShakeOut is an important civil defence initiative and I'm pleased workplaces, schools and families are getting behind it."
The ministry this week wrote to the country's 100 largest businesses and Government agencies asking them to get on board.
ShakeOut will test how much families, businesses and schools know about earthquake preparedness and how they would react if they were in a major quake zone.
