Under the Building Act, the builder has a right to access adjoining properties if necessary to conduct work. What you need to do is send them a dated letter asking permission to access the land - if the neighbor does not reply, then you have automatic and unfettered access to their property by law. If the neighbor replies and says no, then you still have the right to access the property, but need to get the building board involved for specifics (I forget what they are).
Either way you must of course return your neighbors yard to original condition.
If it were me, I'd send the letter as certified mail and raid their letterbox. Then when they complain you show them the building act, the letter, and move the scaffolding in
