A Labour government would reduce Accident Compensation Corporation employer and motor vehicle levies by mid 2009.
The Labour Party's ACC policy, release in Motueka on Tuesday 28 October, pledges to retain the corporation in public ownership.
Labour spokesperson Maryan Street says any suggestion of competition in ACC should sound alarm bells.
She says the Government is still gathering residual levies from when the scheme was privatised in the 1990s by the former National government.
ACC was to be fully funded by 2014 but Ms Street says this date would be pushed out to 2019 under a Labour government, to ease the burden on levies.
The changes would reduce the employer levy by 25 cents from $1.26.
The motor vehicle levy would reduce by about $80 a year.
