Directions to the Event
From the Southern Motorway:
Take the Bombay/Pukekohe Exit 471 heading south-west towards Pukekohe for 2.0 km. Turn left into
Harrisville Road following the signposts to Tuakau. Continue 9.2 km through the main street of Tuakau to a
T-junction with Buckland Road. Turn left into George St and travel 3.8km and cross the Waikato River at the
Tuakau Bridge.
From Wesley College:
From Wesley College turn left onto Paerata Road and travel 6.0 km towards Pukekohe. At the roundabout
when you can see KFC turn left into Stadium Drive and follow this ring road for 700m. Immediately after
crossing the railway bridge turn left into Manukau Rd. Continue straight along this road for 13.4 km through
Buckland and passed Tuakau School until you cross over the Tuakau Bridge.
From Tuakau Bridge
Over the bridge turn left, travel 50m and then turn sharp right up the hill onto the Onewhero Tuakau Bridge
Road. Travel 6.0 km through Onewhero and continue along the main road which becomes
Wairamarama-Onewhero Rd. Travel 6.1 km to a crossroads and turn right into Ponganui Road. Carefully
travel 12.5km along this narrow, winding, metal road, “the Goat Track”, to the Parking area.
Allow 60 min from the Southern motorway or Wesley College and 45 min from the Tuakau Bridge.

Hazards
Usual farm hazards apply. The land is steep in places. Some of the rocks have impassable
cliff faces which are dangerous and which are mapped.
The specific danger in this area are the tomos which are small sink-holes in the ground that you can fall
into, either one foot or your body. We found a sheep stuck in one while course setting. The tomo is a
natural drain hole in the limestone country so they are usually found at the bottom of a depression where
the hole may be obscured by a few ankle-high ferns. Do not test them, they can be very deep. Orienteers
have been known to get lost down tomos! Warn your children.
Ponganui Road is a long, narrow winding dusty, metal road. The locals call it the “goat track”. There are
some one-way small bridges. Take extreme care driving along this road. Particularly watch out for
oncoming traffic since visibility is limited around corners. We will drive along Ponganui Road each morning
and return the same way in the afternoon. However any cars needing to drive against this traffic will be
directed to follow the loop road along Brien Road to get back to the start of Ponganui Road. The loop is just
as quick and will be safer since it will save drivers having to confront many orienteers’ vehicles.
Special Notes
Due to the nature of the terrain every competitor should carry a whistle. There are minimal
thistles on this map so any clothing will be comfortable.
