Canberra's corflute-obsessed politicians will have to follow new guidelines come the next ACT election, after the ACT Electoral Commission recommended new rules on where the staked-signs can be displayed.

While Canberra's streets were awash with corflutes leading up to the October election, so too was social media with complaints.

The ACT Electoral Commission's report on the Legislative Assembly Election for 2016 noted anecdotal references in social media.

The report said social media "indicated a relatively widespread degree of dissatisfaction with the proliferation of campaign signs (principally the signs on stakes known as corflutes) across Canberra's main roads and suburban streets".

The commission recommended an amendment to the moveable signs code of practice.

It would mean corflutes would be placed only on "specified stretches of major arterial roads, outside designated areas that have the special characteristics of the national capital".

Hundreds of votes not counted due to post office delay

ACT election authorities blamed the post office for a spike in postal votes that arrived too late for the October election, and therefore were not included in the official count.

The same report found that 701 postal votes did not arrive in time for last year's poll because of a perceived decline in postal services.

More than 300 postal votes were not counted in the 2012 election because they were received too late.

The 2016 figure represents a 120 per cent increase on the 2012 result.

Of the 701 postal votes not included, 80 per cent were sent from an overseas address.

The report stated the amount of missed votes indicated that the current postal service did not meet requirements for long-distance postal voting.

Taxpayers forked out a record $1.7 million in public funding for parties and candidates.

Funding was increased for the election to $8 per vote, compared to $2 for the previous election.
