I should preface this by stating that no critiscm of the NZIS is intended or implied by the following - it is merely making a slightly unclear situation clear, prompted by discussions with young professionals who weren't aware of the current situation.
The new membership policy introduced by NZIS (I think as far back as 2013) means that there is for the time being almost no point in doing more than what is required to obtain a license to undertake cadastral surveys, when going before the NZIS admissions panel.
Previously, in order to become a voting member of NZIS one had to hold five competencies as verified by the admissions panel. This has been replaced by a requirement to have at least 2 years' post-graduation experience and two referees as to one's good character.
Therefore, unless you are interested in obtaining RPSurv status down the track, it would pay to think seriously if you are holding out for the perfect spatial measurement or more-likely land development engineering project.
Further to this, it would be advisable for those thinking of sitting the NZIS professional entrance exams to have a read through the consultation material released by the NZIS to its members recently. When considering which projects to submit, candidates should consider the potential future structure of the NZIS Registered Professional qualification. It is recommended that you discuss this with NZIS Head Office or a representative of one of the NZIS Streams if you are in any way unclear.
