A slip near Taupo closed State Highway One to one lane for over seven hours last night.
The slip occurred around 10pm near Bulli Point, a Police Northern Communications Centre spokeswoman said.
The road was reopened to two lanes around 5am this morning, however crews were still on site clearing residual debris.
The slip in Taupo followed slips in both Picton and north of Wellington caused by torrential rain at the top of the South Island and the bottom of the North Island.
Meanwhile, residents of a Picton house escaped injury when a landslip hit their home and broke through a wall yesterday.
Just after 4pm the slip smashed through a bedroom wall, Southern fire communications shift manager Karl Patterson said.
The family had left the home, but it was not known if other properties were being evacuated, Mr Patterson said.
The Marlborough District Council said the heavy rain in Picton caused overflows at several points in the town’s sewerage system.
The sewage pumping station in Dublin Street was overflowing into Waitohi Stream and sewage was overflowing through the Kent Street drain into the stream. The Picton Marina was getting overflow from three points in the sewerage system.
The council said Picton’s Waitohi Stream was running very high, causing discolouration in the harbour.
Members of the public were reminded to follow safe hygiene practices if they come into contact with dirty water.
Meanwhile, a slip closed the Rimutaka Hill Road north of Wellington, caused major traffic delays yesterday afternoon.
The road had reopened by 6pm, but NZ Transport Agency regional performance manager Mark Owen said motorists needed to take care on the road.
“We are advising motorists to drive with care as conditions are challenging and continued rain could lead to more slips.”
