Firefighters in Wellington may have to use sea water, and are bringing water tankers into the region as a precaution, should water shortages worsen.
Fire and Emergency is planning for the possibility of level four water restrictions in Wellington, which would mean serious shortages in some suburbs.
FENZ has already brought a tanker into Wellington as emergency water supply, and has plans to bring more if needed.
Brett Lockyer, Fire and Emergency's Acting District Manager for Wellington, says planning for more serious water shortages is well underway.
Lockyer spoke to Ben Strang.
