Duke is number one at the KC Stadium following Boaz Myhill's summer switch to West Brom and has not been beaten in five home league games this season.
Duke said: "I'm really pleased to have played a part in that record. It's six clean sheets in a row at the KC Stadium if you count our last game of the 2009/10 season against Liverpool as well.
"Although it's a positive, it also shows the difference between our home form and our away form at the moment.
"We've kept six clean sheets this season but in the other four games we have conceded 13 goals - that's something we need to address.
"It's important we keep solid at the back. It goes without saying, the more clean sheets you can keep, the greater the chance you have of getting that result."
