Targeted aerial spraying on Mauao has been delayed until tomorrow morning due to wind.
The Waikorire and four-wheel drive tracks are expected be closed from 5.30am to 10.30am.
The closure is to ensure visitor safety during a targeted aerial spraying operation to control a Japanese honeysuckle infestation on the southern face of Mauao.
The Oruahine Track to the summit and the Base Track will remain open and will have signs in place.
