A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Regions experiencing these soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.

Across the North Island, soil moisture levels either decreased slightly or remained the same during the past week. Across the South Island, soil moisture remained near normal or above normal in the central and eastern part of the island during the past week while areas in the west have near normal or below normal soil moisture.

The driest soils across the North Island compared to normal for this time of the year are found in an area stretching from coastal Manawatu-Whanganui northeast to Taupo. The driest soils across the South Island compared to normal for this time of the year are found in far southern Westland District. A small hotspot has emerged in Nelson in the past week.

A new hotspot emerged in the Rangitikei District in Manawatu-Wanganui during the past week. This is the only current hotspot in the North Island. There are currently no hotspots in the South Island.

All previous hotspots in the North Island dissipated this past week due to the heavy rainfall. Substantial rainfall in the past week caused the small hotspot in northwestern Marlborough to dissipate, and no other hotspots are currently in place in the South Island.

The driest soils across the North Island compared to normal for this time of the year are found in parts of Northland, Taupo, and Tararua District. A small hotspot is currently in place in northwestern Marlborough.

The driest soils across the North Island compared to normal for this time of the year are found in Whangarei and Kaipara districts, along with Taupo and Tararua. No hotspots are currently in place in the South Island.

The largest hotspot in the North Island continues to be found in Napier and southern Hastings District. A new, very small hotspot has also emerged this week near Cape Reinga. No hotspots are currently in place in the South Island.

With the recent rain, the soil moisture has generally improved across the North Island since last week. However, the soils are still drier than normal for the time of year in eastern Northland, western Auckland, western Waikato, western Taranaki, as well as Hawke’s Bay, central and southern Manawatu-Wanganui and Wairarapa.

Soils are drier than normal for the time of year in the majority of the North Island, excluding the eastern Gisborne region where the soil moisture is near average. Parts of Queenstown-Lakes District in Otago, the Grey and Buller Districts in the West Coast, northeastern Marlborough, and the Waimate District in southern Canterbury experience well below average rainfall for this time of year, while the rest of the South Island had near normal rainfall.

There are no currently no hotspots, but an area to monitor is in the southern Hurunui District in northern Canterbury.

Hotspots in the North Island are located across Gisborne, the Tararua District, and in parts of west coastal Taranaki. The only hotspot in the South Island is in Southland.
