Sounds to me like the medical form is missing a check-box of some sort.
Way back in 2018, my fiancé had his medical only 3 days before the interview, and they did not have the result and therefore couldn’t approve the visa until received. It only added a week or so to the process.
I know that post-Covid, operations even at “easy” consulates such as Auckland are not what they once were, but I think you’ll hear from them shortly.
Keep us posted!
