The objective of the institute is to promote the profession of landscape architecture throughout New Zealand, and to promote the appropriate and sustainable protection, planning, design, intervention and management of our landscapes. As a collective of professionals, we have a responsibility to assist our members in improving their general and technical knowledge through Conferences and a Continuing Professional Development (CPD) programme.

Members must undergo an examination in professional practice before becoming a Registered Member, and are encouraged to extend their knowledge and skill in their preferred areas of practice. Members of the institute must adhere to an agreed code of conduct and should it ever be necessary, the public can seek redress with the Institute over the conduct of a member.
