Hey Guys.

I was viewing the information incorrectly and so phrased the problem incorrectly.

The waits were not due to the insert, but the select statement that was being used as the source for the insert, which makes things a lot clearer.

As inserts cant be parallel, the parallel plans were coming from the select statement used as the source for the insert.

Next step is to have a look at that statement and identify areas where it can be improved by rewriting, indexing etc.

Apols for any time wasted due to my incorrect posing of the question.
