Soil moisture

Soil moisture on 31 March

Conditions improve in the North Island

Moderate soil moisture deficits continued, particularly in eastern regions, but rainfall brought some relief to Waikato and King Country. Conditions in much of the North Island were near or just below average at the end of March

Significant soil moisture deficits in Otago have now spread to parts of inland south Canterbury, central Marlborough and the Canterbury Plains. Regions east of the ranges were drier than average by the end of March, but the situation was not as severe as at the same time last year.
