Storm: What you need to know - Wed 9 July
Drivers are being asked to maintain caution as strong winds and rain continue to make conditions dangerous in Auckland and Northland.
The NZ Transport Agency is advising people to take extreme care on state highways and roads.
For the second day, the speed limit on the Auckland Harbour Bridge has been lowered from 80 to 70kmh.
The Transport Agency has advised motorcyclists and people using campervans and other high-sided vehicles to consider using State Highways 16 and 18 as a safer alternative between the North Shore and the south side of the Waitemata Harbour.
"The bridge does remain open and we did restore the 80kmh limit overnight, but there have been some wind gusts over 80kmh and the lower speed has been introduced again to help keep people safe," said the Transport Agency's Regional Journey Manager, Jacqui Hori-Hoult.
SH11 between Paihia and Kawakawa is closed due to flooding, with the NZ Transport Agency urging drivers to avoid the area if possible. Fallen trees have closed SH12 north of Dargaville on the western side of Northland between Kaihu and Oranoa.
NZTA is warning drivers to be cautious on SH1 south of Whangarei after the severe weather caused large potholes to develop.
A small number of regional services in to Auckland International Airport have been cancelled. The airport's website showed flights from Hamilton, Kerikeri, Nelson and Whangarei had been cancelled.
Ferry services to Devonport, West Harbour, Pine Harbour and Halfmoon Bay which were cancelled have been restored. The ferry to Waiheke is again stopping at the Devonport terminal.
Ferries to Northcote, Birkenhead and Bayswater remain cancelled.
