Hi. Is your degree on the List of Qualifications Exempt from Assessment (
http://www.immigration.govt.nz/opsmanual/35171.htm) or did you obtain an IQA from NZQA? The Case Officer may need to check that the degree content is indeed relevant to the job you have been offered if you need those points to reach 100. I had never had an academic transcript because my first UK degree and post-grad diploma were so long ago that this was just not the way it happened. However, I managed to obtain a transcript very quickly from two different universities. I am sure you could obtain this quickly.
In terms of the partnership evidence though, this could be tricky. You can show simultaneous flights to and from China, I imagine, maybe a letter from the school, confirming that you are a couple and lived together in China. Do you have a joint bank account? You will really need to think about what evidence you can find of living at the same address, sharing your household expenses and socialising together - trip to see the Great Wall??? Photos there? Hope it goes well for you.
