Wellington Electricity said around 70 people were without power in Upper Hutt, with the outage mostly affecting those in Akatarawa.
There will be restricted sailings on the East by West ferries this morning due to adverse weather conditions.
Wellington City Council spokesman Richard Maclean said the problem was heavy, persistent rain falling all day Sunday and overnight into Monday.
"Everything is saturated, we're starting to get reports of slips coming down.
"They're mainly on roads like the Makara road which is a twisty, narrow little road.
"At the moment those types of roads aren't completely closed, but people should take a lot of care out there because there could be slips around the corner, and more slips could come down this morning."
Maclean said there was surface flooding in various areas, so drivers should take extra care in case what looked like a small puddle was actually much deeper.
