Any person can be a member of the Society. New members usually join one of the affiliated groups and pay an annual group membership fee that includes the Society subscription of $35.
All members of affiliated caving groups are members of the Society.
The single membership fee includes a subscription to the newsletter "Tomo Times" and the NZ Speleological Bulletin.
Second or subsequent adult members of a family living at the same address can become family members by paying an additional $25 rather than the full $35.
Members under the age of 18 can become youth members for an additional $5 each. Family and youth members do not receive copies of the Society's publications.
Publications membership provides individuals or organisations with NZS Bulletins and Tomo Times. This membership class has no other benefits and does not include voting rights. Publications subscription is the same as single member subscription.
NZSS and your caving group may provide copies of the membership list, (paper or electronic) to Waitomo Caves Discovery Centre, Department of Conservation, and other entities deemed as appropriate.
Life Membership of the Society can be conferred on a member of the Society by Council in recognition of meritorious achievement in caving at a national level.
