Essential services have been fully restored to the Horowhenua town of Levin a week after storms cut power and contaminated the water supply.
More than 30km of power lines were downed by winds, cutting power to 30,000 people.
The lines company Electra says it has finished repairing remaining damaged lines and all its customers have now been reconnected.
The Horowhenua District Council on Thursday lifted a direction that residents in Levin and surrounding towns should boil their water before drinking it. The council says people can be sure their water is now safe.
All roads are now open.
However, MetService says a new cold front on Friday will bring snow to eastern areas of the South Island and the North Island central plateau.
