Despite there being rain in the city from yesterday afternoon and throughout the night, very low levels had been recorded, according to MetService.
In the past 24 hours, 12.55mm of rain was recorded in downtown Auckland.
At Auckland Airport, 14.2mm of rain was seen there in that time period and just 1.5mm of rain was recorded in Whenuapai, west of the city.
"Definitely not enough to fill the tanks," meteorologist Larissa Marintchenko said.
"There'll be some rain again on Wednesday, but not significant rain. There's rain again on Friday, but still not significant enough."

In other parts of the country, a heavy rain watch is in place in the ranges of eastern Bay of Plenty.
People in the area are being warned that rainfall amounts may approach "warning criteria". The watch is in place until 1pm today.
There are also watches in the Tararua Range, Tongariro National Park and the Kaimanawa Range; as well as the ranges of Buller, north of Westport, Nelson from Motueka eastwards and the Marlborough Sounds and Richmond Range - including the Rai Valley.
Those watches are in place until this morning and locals are advised to keep an eye on updated weather forecasts throughout the day.
Heavy rain fell in the Mt Taranaki area yesterday and more was expected overnight.
Locals were also told the heavy rain could cause streams and rivers to rise rapidly; while motorists were encouraged to be careful on the roads as surface flooding and slips were possible as a result.
South of the country, some snow is said to be likely in the Southern Alps today - mainly around Canterbury, WeatherWatch says.
