Soil moisture

Very dry soils

There were still significant soil moisture deficits at the end of April in the southwest of the North Island, and in Marlborough, south Canterbury, and much of east and Central Otago.

Some areas that were particularly dry at the end of March, including eastern areas of the North Island and the South Island east coast from Kaikoura to north Canterbury, recorded improved moisture levels during the month after near or above average rainfall.
