Thunderstorms have again hit the Kapiti Coast region north of Wellington, uprooting trees and bringing down power lines.
High winds brought down two large trees and ripped part of the roof off a beachfront house in Paraparumu on Wednesday.
Emergency services have been securing flying roofing iron, and a shed in Manly Street in Paraparaumu has been blown off its foundations.
The Fire Service is warning people to keep away from downed powerlines.
On Sunday, three people were injured, power cut and trees and power lines brought down in the Kapiti Coast town of Waikanae when a small tornado swept in from the sea.
MetService said on Wednesday morning the area could expect thunderstorms, bringing hail, for several hours.
It has warned that the same northwesterly weather pattern could bring small tornadoes to the Marlborough Sounds and Farewell Spit on Wednesday.
The Emergency Services Manager at the Marlborough District Council, Ross Hamilton, says it is the first time in almost a decade he has received a warning for small tornadoes.
Mr Hamilton says people should be ready for thunderstorms and winds up to 110 km/h.
