From Havelock North head east via Te Mata Road. After about 1km, turn right onto Simla Road, and then, after another 800m turn left onto Te Mata Peak Road. The summit car park is about 5km from here.
There are very high and steep cliffs below the summit view point. Keep behind the barriers. Some of the tracks in the area also traverse very steep ground and require care.
You can drive to the car park at the top of Te Mata Peak, or start from the car park lower down at the Te Mata Park gates where there is a map of several tracks for walkers or mountain bikers that lead to the summit. If you chose one of these options the accessibility becomes 'moderate'.
