The requirements for LTSSL are these.
Required standard
One of the following qualifications:
- A relevant Washington Accord accredited undergraduate engineering degree (listed)
- A relevant qualification comparable to:
(a) a Bachelor of Engineering (NZQF Level 7), or
(b) a Bachelor of Engineering with Honours (NZQF Level 8)
- A relevant qualification at NZQF Level 7 or higher with a letter from IPENZ certifying that the degree and any further learning meets the academic requirements for registration as a Chartered Professional Engineer in New Zealand
OR
NZ registration as a Chartered Professional Engineer by the Institution of Professional Engineers New Zealand.
Notice, it says "Bachelor of
Engineering", and you say you have a Bachelor of Industrial Technology.
Qualifications are counted as exempt from assessment when the course has been checked out already and found to give qualifications equivalent to a certain NZ Level. So your degree has been accepted as a full Level 7 without any difficulty. But that checking does NOT say it is equivalent to any particular NZ degree, such as a bachelor of engineering, and THAT is what the CO would need to see to grant you the points from column 4.
To get the LTSSL points, you would have to either get an IQA done to say your degree is equivalent to a Bachelor of Engineering, or you would have to get an IPENZ letter saying it meets the requirements.
