A truck carring a 64m-long wind turbine blade has tipped on its side along State Highway 45 in Taranaki.
The truck slid into a ditch and tipped over shortly before 8am while negotiating a bend at the intersection with Hampton Rd, south of Ōkato.
The NZ Transport Agency said as of 12pm there was still only one lane reopened on SH45, and a stop-go was in place.
A contractor has been called to lift the trailer out of the ditch.
