Backcountry Tramping South Island April

Hi everyone, my name is Nora and I am 25 years old. I arrived in New Zealand in September and have done a fair bit of walking since then. So far I managed to do 8 out of the 9 Great walks, four Volcanoe Summit Climbs and another handful of Backcountry walks. I am really keen to do some more tramps in the South Island in April including Nelson Lakes, Rees/Dart, Caples/Greenstone, Hollyford and the Milford (off-peak). It would be great to have people join me! Unfortunately, I do not have a car. Well, hopefully we can work something out!
