Auckland and Christchurch have woken to 99 per cent humidity

Northland and Auckland’s sodden conditions have shifted to the southwest overnight, with Tauranga drenched in 59mm of rain in the past 12 hours.

Marlborough, which had been pelted by 198.5mm of rain in the past 24 hours in its Western Ranges, is beginning to come through the worst of it.

In Nelson, the Nelson Tasman Emergency Management Group reported rivers had risen rapidly in the district causing localised surface flooding and slips.

But the worst may still be to come with Tropical Cyclone Gita upgraded to category 4 overnight and weather modelling showing it could find its way down here.
