Soil moisture

Low soil moisture in Northland

Soil moisture deficits increased in much of Northland during April. At the end of the month, moisture levels were lower than normal also in parts of western Bay of Plenty, Manawatu, Nelson, central Marlborough, and the Mackenzie District. Moisture levels were higher than normal in Hawke’s Bay, Wairarapa, and Southland.
