Inserting new page in Microsoft Word

"I'm not sure I understand your question completely, but try this:

remove the flowchart (cut and paste into another document, etc)
insert a next page section break (insert > break > section breaks > next page in Office XP)
copy the flowchart back into your original document before the new section break"

"I realize this is an old thread but hopefully this will help somebody. I was having a similar problem not being able to insert a blank page after I drew a flowchart in Word 2013. To create the next page:

I selected all the objects I had created on the page and grouped them into one grouping. You could save time by creating the group when you first start (i.e. canvas)
Selecting either all the objects (if not grouped) or the single group gives a new menu of Drawing Tools -> Format at the top of the screen.
With the group selected, click the button labeled Wrap Text and select the option Through. That will take it out of line with the text.
At the top of the page, or anywhere in the page for that matter, go to Insert -> New Page. You should now have a new blank page after your chart."
