所以这种邮件就是最终拒绝了吗

当时我申请的140分获邀,现在对方声称我只有135分受到认可(已经补了N次材料了)

Therefore, we are not satisfied to recognise your second claimed employment and no points can be awarded accordingly.
We would proceed to make a decision on your application with the current evidence and information on file, we would also keep you informed of the outcome.

看起来新西兰移民部最终认为你不够140分,没希望了。

如果最终因为不够140分被拒绝有什么影响?以后申请AU的移民会受到此事件的影响吗?

135也是有选中机会的,等最终outcome吧。
