Hi Miri, you can find the bus and train timetables on www.metlink.org.nz

It is all good for people to stay at my place the night.  Come drink. Be merry and find your way home the next day.  At the moment we have 2 free bedrooms and even a spare bed.  There is some bedding around but I would recomend bringing a sleeping bag if you have one.

If you do need to get home, no doubt there will be people driving.
