A new "slow for kōkako" road sign in Pirongia is the first of its kind in New Zealand.
Motorists are being advised to take extra care on Grey Rd due to nearby kōkako activity.
Keep an eye out for kōkako swooping across the road or hopping along the ground.
A pair of the precious birds are living near Grey Rd, close to the carpark at the top of the road.
