Reverting to my earlier response on this topic, all the pertinent documentation and data is included in the various publications.
Specifically: The basis of approval for operation in New Zealand is contained within this document.

The basis for acceptance and issuance of this document is the EASA TCDS EASA.R.140.

This Note contained within the Type Approval Report requires compliance with the requirements specificed in Information Letter AB206-06-004
https://www.caa.co.uk/uploadedFiles/...-004%20(2).pdf
Thus the requirements of this letter are specifically incorporated into the Airworthiness requirements and limitations of any AB206 on the NZ register. There is provision within the IL to allow for differing policy based upon the authority having jurisdiction over the helicopter, but this would have to be specifically approved and issued, and in the case of NZ certification does not exist, because the Type Approval Report specifically requires compliance with this requirement.
In response to Krypton John, the answer should be no, there is no difference if the configuration may be identical - this is what went on for years The issues lie entirely in the certification basis and approvals for the parts. Bell have also issued specific guidance on this matter.
