Above average soil moisture levels from Auckland to Christchurch
High January rainfalls lifted soil moisture levels in many areas from Auckland city south to the northern half of the South Island.
Northland, Otago, and Southland total soil moisture storage was mostly lower than average at the end of the month. However, top soils in south Canterbury and Otago were generally moist following the rain.
Soils in most parts of the country had more available soil moisture than at the same time last year.
