Auckland and northern New Zealand could be in for more tornadoes on Friday.
The MetService says the weather conditions needed to create tornadoes are lining up.
Chief forecaster Peter Kreft says several lines of thundery showers are due to cross the north and west of the North Island and their pattern indicates that tornadoes may form.
Mr Kreft says it too early to say how likely they are, or where specifically they might hit, but MetService will issue more information on Friday.
In the meantime, he says people should be aware of the advice for staying safe in a tornado, including taking shelter and getting as low as possible.
On Tuesday one man died, 14 were injured and millions of dollars of damage was caused when a tornado hit Auckland's North Shore.
