不需要自己清华认证，豁免学历也可能要求 NZQA 认证，中国的 certified copy 一般公证处公证，新西兰的可以用警察，政府官员这些。证明夫妻关系的官方要求不完全适合国内情况，看看有没有两人寄到一个地址的快递单。
Qualifications listed (unless an exception is stated) are New Zealand awarded qualifications on the New Zealand Qualifications Framework (NZQF). Overseas qualifications must be comparable to the standard of the New Zealand qualification listed. Overseas qualifications therefore require an International Qualification Assessment (IQA) from the New Zealand Qualifications Authority stating the comparable NZQF qualification.
Despite the fact that the List of Qualifications Exempt from Assessment provides that a specified qualification qualifies for certain points, an applicant or an immigration officer (by requesting the applicant to do so) may seek a IQA or QAR of any particular qualification. Where this occurs, the most recent NZQA assessment will prevail.
