Manager Justin Edinburgh says his team could have scored even more as they overtook Salford City.
The Ammies’ dropped points at home to Ebbsfleet couple with the O’s 4-0 victory means the East Londoners are top again.
“I think we had a real purpose and intent about our play,” said Edinburgh.
“Even if we went on to get a couple of more goals I think it would be justified. Macauley Bonne could have celebrated his birthday with a hat-trick - it wasn’t for the want of trying!
“If you look at Havant’s results, bar one match they have only been losing by the odd goal.
“We knew we had to have a positive mindset and to try and get the early goal which we did.”
Edinburgh added: “Credit to Havant as they didn’t give in. We just needed to get our goals at the right times and we managed to do that.
“We were a very good unit, we moved the ball well and we look decisive.”
