Chiefs Super Rugby co-captain Liam Messam says that errors and poor discipline is costing his team dearly as they look to win their third successive title.
Super Rugby Champions the Chiefs have won back to back titles in 2012 and 2013 but have only won one match in their last six outings.
The Chiefs still lead the New Zealand Super Rugby conference after nine matches. They have won four and drawn two and lost two matches so far this season.
Last week the Chiefs were beaten 17-18 at home by the Crusaders and were humbled 41-23 by last year's Super Rugby finalists the Brumbies in Canberra this week.
While the Chiefs still look capable of retaining their title, their mid-season form wobble must be worrying the coaches in Hamilton.
The Chiefs won their first three matches but then suffered a shock loss in Perth to the Western Force.
Two draws in South Africa followed but by then the Chiefs had picked up a habit of starting slowly but bouncing back in the second half.
After the Chiefs trip to South Africa they appeared to have lost the slow starting habit when they beat the Rebels 22-16 in Hamilton but faded late in that match and allowed the Rebels back into the match.
Last week the Crusaders surged in the second half and ground out the victory but the slow start habit reared it's head again in Canberra against the Brumbies and by half time they were trailing 13-6.
By the 63rd minute the Brumbies had raced away to a 27 point lead at 36-9 before the Chiefs scored two late consolation tries.
A frustrated Messam said after the match some of the basics and their discipline was costing them.
"We made some basic errors with the football and our discipline is letting us down along with basic handling errors," said Messam.
"Full credit to the Brumbies. They really stuck it to us and put pressure on us."
The Chiefs travel back to Hamilton where they will face the Lions who have slipped to a three match losing streak after a strong early start to the season.
