Auckland Airport issued fog restrictions early this morning but international flights are not affected.
The airport's website shows flights from Napier, Gisborne, Blenheim, Tauranga, New Plymouth, Palmerston North, and Whangarei are cancelled.
Several other services are delayed including from Whangarei, Bay of Islands, Palmerston north and Nelson - however it is unclear how many of these are from fog.
Domestic flights to Wellington, Christchurch Dunedin and Queenstown have not been affected.
