Four tracks and a campground near Cape Reinga will remain closed for at least two more weeks while the Department of Conservation investigates reports of packs of feral dogs.
Landowners and visitors have said four packs of dogs, about 15 animals in total, are roaming between Hukatere on Ninety Mile Beach and Te Werahi Beach just west of Cape Reinga.
DoC closed Twilight campground and four tracks in Te Paki Recreation Reserve on April 1, initially for seven days because of fears for public safety.
That has now been extended as a precaution by another two weeks, DoC Kaitaia acting area manager Abe Witana said.
"Public safety remains our number one priority. Over the next few weeks we are going to undertake further monitoring using trail cameras, visual surveillance and detailed collection of sightings people have had on and around Te Paki Recreation Reserve,'' he said.
