The Nelson Speleological Group (NSG) are a caving club situated in Nelson, New Zealand that has around 90 active members.
We are blessed with arguably the most exciting and challenging caves in the country, including some that are of worldwide significance. Come join us and be part of some of the last true exploration of our country.
As well as adventure and exploration, we also value the conservation and protection of our caves. They were formed millions of years ago and most have never seen human footsteps, so it is vital that we treat them with respect and care so that future generations can also enjoy and learn from them.
