Hillside remains unstable

22:35, Jul 22 2012

‘‘Large amounts’’ of unstable material remain above a Horowhenua road closed by a slip.

While Gladstone Road itself is clear an investigation by abseilers yesterday found the hillside was still unstable.

About 3,000 cubic metres of material came down on the road on Wednesday cutting about 20 residents off from nearby Levin.

A four-wheel-drive track over private property has since been opened for residents but Horowhenua District Council is warning the road will be closed for several days.

The assessment by geotechnical abseilers yesterday found large amounts of unstable material was still sitting high up on the slip site.

There is also significant cracking in the land surrounding the slip, which increases the instability of the site.


The forecasted rain over the next week will assist in bringing down the unstable material onto the road the council said. The road would remain blocked until it is deemed safe for traffic.

Access for residents remains open via the Denton Road gate. Security personnel are managing this access way to ensure the safety of residents using this route, and will be on site 24 hours a day.

Users of the Trig walking track are advised to be aware of vehicular movements on the track for the next few days. This track is being regularly monitored to ensure the safety of those using it.

Residents can contact the Horowhenua District Council on 06 366 0999 if they need assistance.
