Auckland Transport said ferry commuters should also “expect possible delays to all Bayswater, Birkenhead, Devonport, Half Moon Bay, Hobsonville ferry services, due to fog in the Waitemata Harbour”. 

A MetService spokesperson said a mix of moist and warm conditions overnight made for “perfect fog weather”.
