Monckton Reserve and Walkway in Central Hawke's Bay has been closed to the public because a dangerous bull is on the loose.
Department of Conservation said checks over the weekend confirmed the bull is camping in the area and the reserve will remain closed until the animal can be captured.
A local farmer's efforts to contain the bull were thwarted at the weekend because the beast simply walked over the fenced area he created.
Conservation Services manager Dave Carlton said the bull poses a big threat to the public.
"Some parts of the track are very narrow with little room to manoeuvre so meeting a bull on the track would be a very dangerous situation," Mr Carlton said.
