Andrew Geddis: Otago University Law Expert on the filling of the Port Waikato seat after Neil Christensen's death

National is now very likely to get an extra seat in the next Parliament.  The traditionally safe National seat of Port Waikato will now be determined in a by-election on November 25, following the death of ACT's Port Waikato candidate Neil Christensen.  In the meant time the 120th seat will be filled by a list candidate, likely to be from National's list.  Otago University law expert Andrew Geddis told Mike Hosking that it's due to a rule that we inherited from the First Past the Post system.  LISTEN ABOVE See omnystudio.com/listener for privacy information.
