Haas Road is parallel to 19A. It can be accessed via Thomsom Road or Hilton Road.
From Courtney head south on Cliffe Avenue towards Royston. 2 km past 29th Ave. turn left onto Thomson Road. Thomson Road will turn to the right and become Haas Road. On your left, 4026 is in the heavily wooded section. Look for the red brick pillar with the house number and small, green sign on it. The driveway splits in two, please keep to the right. Should you miss Thomson Road, take the next left, Hilton Road. Turn left sharply as you enter Hilton to get on Haas Road. 4026 will be on your right from this direction.
If you get to the traffic light at Royston Road, you've gone too far.
