Whangarei District Council said possible rain was forecast in coming weeks, however it would take a significant amount to make a difference to water catchment levels in Kaipara.

River flows in the Far North District are presently at a healthy level with some at significantly higher levels compared with the same time last year, despite ongoing dry weather.
The Far North District Council's Water Shortage Management Committee reviewed data on water sources on January 13 and said rivers that showed significantly higher levels included the Waitangi River which supplies water to Paihia, Ōpua and Waitangi— towns that are typically inundated with summer holiday visitors.
"While there are currently no water restrictions in the Far North, the National Institute of Water and Atmospheric Research (Niwa) is predicting drier than normal conditions over the next few weeks," FNDC general manager infrastructure and asset management Andy Finch said.
"The Water Shortage Management Committee will continue to monitor water sources closely over this period and meet again in two weeks. The council asks Far North residents to keep using water sensibly in the meantime."
