There is a good chance of thunderstorms to hit the country again this weekend, so make sure you're prepared.
Severe thunderstorms with localised downpours of 25-35 mm/hr of rain are expected to begin tonight, the Met Service says.
The downpours will be the main risk for these thunderstorms with the heavy rain warnings in place for northwest Nelson, Mt Taranaki and eastern Bay of Plenty.
Northland, Auckland, the Coromandel and Rotorua are also not let off lightly, with periods of heavy rain expected to hit tonight and into tomorrow morning.
Heavy rain, especially in localised heavy downpours, can lead rivers and streams to rise rapidly, and may produce slips and localised surface flooding, the Met Service says.
Over Easter weekend 6000 Auckland homes were affected by power outages due to a storm.
"Before an emergency situation people worry about their resources, mobility, connectivity and loved ones. Preparing for the unpredictable can help build the resilience of yourself and loved ones if you're in an emergency," says chair of the Auckland Civil Defence and Emergency Management committee councillor Sharon Stewart.
Auckland Council research shows only 52 percent of Aucklanders have the necessary emergency items needed to survive a disaster.
However, last Wednesday more than 100,000 people viewed the Met Service online and the council's Our Auckland site to get informed on the storm.
"This suggests Aucklanders are intensely interested in making sure they know what they need to do if there is a potential of an emergency, however preparations are not something that should be left until the last minute," says Auckland Civil Defence and Emergency Management director John Dragicevich.
For Auckland localised downpours with rainfall rates of 25mm to 35mm per hour are possible, and a Thunderstorm Watch is in place.
