A weekly update describing soil moisture patterns across the country to show where dry to extremely dry conditions are occurring or imminent. Regions experiencing significant soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.

Local marine farmers, scientists and iwi have joined forces to turn the fate of wild mussels around.

Two kororā chicks – also known as little blue penguins – have hatched in Wellington. They were born in a protective nest box in Evan’s Bay, set up by NIWA and Places for Penguins, in partnership with the Urban Wildlife Trust.

The NIWA and MetService assessment of named tropical cyclone (TC) activity indicates 9 to 12 named TCs could occur in the Southwest Pacific basin between November 2021 and April 2022. The seasonal outlook is for normal to slightly above normal activity in terms of overall named TCs in the region.

Bottom lining is the installation of a flexible covering over the top of beds of aquatic weeds, similar to using weed matting in home gardens. The lining is held in place by weights (e.g., rocks or sandbags) or by pinning. This control method is also called ‘benthic barriers’.

CliDEsc is a web-based content management system and product generator library developed by NIWA in consultation with National Meteorological and Hydrological Services in the Pacific region, and with the Australian Bureau of Meteorology.

The project aim was to harness the filter-feeding capacity of native freshwater mussels on rafts to assist in lake restoration.
