I have yet to experience this one myself as it is brand new but here is what the Department of Conservation says:

This track begins at the top end of Plateau car park. Walk up the access road toward the suspension bridge and ski field. At the flying fox there are good views of the Manganui Gorge and the summit of Mount Taranaki.

Allow 20 minutes to walk to the bridge and a further 5-10 minutes to the ski field. The track is in the alpine environment and exposed to the weather. It can be very icy in winter conditions.

Manganui Gorge suspension bridge

The 100-metre bridge sits 49.5 metres above the gorge floor. It is designed for a lifespan of 100 years and to withstand the sub-alpine harsh environment, including strong winds and changeable weather conditions experienced in the Manganui Gorge. The stunning balustrade panels were designed by Ngāti Ruanui and depict the various phases of avalanches.
