Soil moisture

Soil moisture recovery in northland

Northern soil moisture levels rose following high rainfalls particularly in Northland and Waikato, but also in Manawatu and Horowhenua. At the end of May, soils were unusually wet from Bay of Plenty down the east coast to Kaikoura. Otago soils remained a little drier than average in some places.
