Water delivery is classified as an essential service and, while intermittent rain has slowed demand a little, carriers are experiencing steady business that is expected to continue until winter.
Andrew Kevey of Water 2 Go in Whangārei said demand was "pretty steady", down to about half of what his company did when drought was declared in Northland in February.
He's using two trucks and is averaging six loads a day.
"In summer, the demand was nearly double but it's still pretty steady at the moment. We'll keep going until winter or until we run out of water,"
