A pet rescue operation was under way last night to find animals left behind when people fled the tornado.
A 14-strong Civil Defence response team of trained volunteers entered the cordoned-off zone to search for scores of cats, dogs and other pets.
Auckland Council Civil Defence boss Clive Manley said a number of residents had no choice but to leave their pets behind and the response team, supported by SPCA officers, went back to collect pets and reunite them with their owners.
The forecast for severe weather overnight had the potential to create further problems for people affected by the tornadoes and storms.
Wind gusts of up to 100km/h and intense rainfall were due to hit Auckland at midnight.
