Yes, Manganui (up Mt Taranaki) got clearance from DOC to open early! There is snow in the forecast for Wednesday/Thursday and they have good coverage on the T-bar. Manganui is on my list of places to go this winter.
The next field that looks set to open is Mt Hutt in the South Island on the 30th May.
