Auckland, North Island flooding: Tuesday's weather forecast - what you need to know

There's been a brief reprieve from the rain for Aucklanders overnight but more is on the way.

Most of the Super City is under an "orange" heavy rain warning.

In Northland, a "red" heavy rain warning came into force on Tuesday morning until at least early on Wednesday. That red warning will also come into effect in Auckland north of Orewa from 4pm.

Anyone travelling is still being advised to take extreme care, with many roads still impacted by slips and flood water.
