It’s unfortunate but hardly surprising. 

Around 10km of highway through Northland's Brynderwyn Hills has been closed since February for repair work. 

It had been due to reopen in a couple of weeks, but a slip has put paid to that. 

Whangārei Mayor Vince Cocurullo told Mike Hosking that delays had to be expected. 

He says around 40-thousand cubic metres of soil will now have to be moved, and it's currently moving as if it was sand.
