"Farm staff go down on the farm track and pull them out but it doesn't happen all the time; we're having people stuck in the middle of nowhere."
Mr Te Wake said cars coming from Te Paki Stream Rd faced the danger of a 1.8m to 2m drop-off, which was hard to see in the dark or twilight.
"For public safety, we have to close it [the stream] until Mother Nature works with us and puts it the way it used to be," he said.
Drivers coming from south of Kaitaia, such as Aucklanders, seemed to have the most difficulty with the track, Mr Te Wake said.
"They have these big SUVs but they don't know how to drive them. They don't realise they're not amphibious or that there is such a thing as quick sand," he said.
"We don't want our visitors to the region being hurt or inconvenienced."
The Department of Conservation will put up signs later this week to warn of the closure.
Mr Te Wake said the closure would not stop people parking in a safe place and playing on the giant sand dunes the area was famous for.
