"There's also a few more water carriers around than then, but we've had a lot of people ringing up for quotes," she said.
"Just today we had somebody ringing up from near Dargaville for a quote as they can no longer get water from Dargaville."
Whangarei Heads homes and baches were providing many customers at the moment and one Heads' resident spoken to by the Northern Advocate said his tanks were the lowest they had been for more than 20 years.
Dargaville Water Carriers said it was filling up 10 water tanks a day up until last Friday when the Kaipara District Council stopped any further water being taken from the Dargaville water supply.
The company now had to take water from the Ruawai supply, which added costs and meant it could only do four loads a day, a spokeswoman said.
"We were almost double what we were doing last year and even more than in the 2010 drought, but the restrictions mean we can't do as many now. The town supply has to come first," she said.
She urged people wanting a tanker of water to book as soon as possible, but accept that there may be a wait.
A spokeswoman for Kaitaia Water Carriers, which supplies the area from the Hokianga and Mangonui north, said while the company was far busier than normal delivering water, it was far worse in 2010.
"In 2010 the drought started a lot earlier than this one, but we have seen an increase this year, with things starting to pick up about three weeks ago," she said.
Rain is predicted for Northland this weekend, but it's not expected to be enough to break the drought.
