Slip blocks gorge

Waihi Leader - - News -

The Karanga­hake Gorge is once again un­der the spot­light af­ter a large slip on Satur­day night.

NZ Trans­port Agency Waikato sys­tems man­ager Karen Boyt says the slip was caused by the re­cent rain­fall. “It has made the hill­side un­sta­ble.”

She says in­ves­ti­ga­tions were un­der way. “As part of our in­ves­ti­ga­tions we are as­sess­ing what can be done to pro­vide a more re­silient sec­tion of high­way. The ma­te­rial above this sec­tion of high­way is a mix of boul­ders, ash and silt, which makes this area vul­ner­a­ble to slips, es­pe­cially with large amounts of rain. “How­ever, we mon­i­tor the area reg­u­larly and con­tinue to as­sess what can be done to pro­vide a more re­silient sec­tion of high­way.”

Un­sta­ble boul­ders had also been re­moved, and there was other work done in Septem­ber, she says.

“We re­moved a sec­tion of un­sta­ble ma­te­rial im­me­di­ately east of the most re­cent slip in Septem­ber this year.”

The cost of that was $33,729.82, she says.

The agency ad­vised peo­ple to al­low ex­tra time for their trip through the gorge and to drive with care.
