The Northern Territory Electoral Commission continued the vote count on Monday following Saturday night's poll, and the contest is tight in six seats that are yet to be called.

The man Mr Giles knifed as leader in 2013, Terry Mills, has returned to politics and is contesting the seat of Blain as an independent, and is currently leading Labor's Damian Hale by 101 votes on a two-candidate preferred basis, with just over 62 per cent of the vote counted.
