NPDC crews kept busy dealing with more than 40 slips as clean up continues

Local News Our Work Public Notice Road Closure Featured news

Following several days of heavy rain, NPDC staff and contractors have so far dealt with more than 40 slips – many that have blocked roads and is monitoring roads and three ongoing wastewater overflows.

“Our teams have been absolutely flat-out since Thursday in trying conditions clearing up and making safe as many of our roads, walkways and parks as possible,” says NPDC Group Manager Planning and Infrastructure, Kevin Strongman.

“While the weather looks like it is starting to clear, there are still several roads at risk of further slips occurring, so we remind people to be cautious while they are out and about over the next few days.”

He says it is going to be several weeks before we have a clear picture on what more permanent solutions maybe needed to repair the roading network across the district.


This morning, all roads, except for Upland Rd between SH3 and Upper Lepper Rd were open where flooding levels will be checked again this afternoon.

Crews are out today cleaning up slip material on:

  • Okau Rd
  • Waitaanga Rd.
  • Mangatoro Rd.
  • Mohakatino Rd.
  • Waikaramarama Rd.
  • Pukearuhue Rd.
  • Piko Rd.
  • Matapo Rd.
  • Mangamaio Rd.
  • Tarata Rd.

There has also been a slip in the Uruti Tunnel this morning and is closed until further notice. It is unsafe to be inspected in person so will be done remotely.

Water and wastewater

As rain continued to fall this morning, we are keeping an eye on the reticulation system.

  • The portaloos placed in Waitara and Inglewood at the weekend will stay in place for now and be revaluated later this week.
  • We’ve been keeping in touch with impacted residents offering support and assistance.
  • We are still asking people in these areas to reduce water use to take pressure off the wastewater system eg: not using their washing machine and taking shorter showers.
  • Inglewood Oxidation Ponds: the consented discharge is continuing into the Kurapete Stream, but the volume of the flow is dropping.
  • Colson Road pump station: this is overflowing into the Puremu Stream (which leads to the Mangaone Stream and Waiwhakaiho River).
  • The consented discharge into the Waitara marine outfall continues but the volume of the flow is dropping.
  • Crews in Waitara are cleaning up sewage overflows on some streets.
  • The morning inflows the volume of water coming into the New Plymouth Wastewater Treatment Plant was more than it is designed to handle. This has led to the discharge being non-compliant with our discharge consent.


  • Log jams along Waitara and Manganui rivers are also being assessed today but won’t be able to be dealt with until river levels drop and the work area is safe.
