The first batch of special prizes have been distributed.
Google says "have" but I find it hard to believe.
I think Google is wrong too, but I am curious how you asked.
There is only one batch being distributed, so it should be 'has'.

Refers to the batch as a unit -- this is appropriate where the batch is given away in a single lot. (Which of course, is obviously not the case here).
