The current strength of the corporation's books is also a significant factor aiding the Government's target of returning to surplus by 2014-15.
Asked whether the good news about ACC strengthened the case for larger and sooner cuts to levies in line with advice last year from both ACC itself and the Ministry of Business Innovation and Employment, Ms Collins said: ``We have to look at the wide picture as well".
"We've made no secret that as a Government we want to get back into surplus by 2014-15 and it would make no sense to lower one side and then have to raise something else."

Party members sat down to lunch this afternoon with a view of a drizzle moistened trio of protestors outside including activist Penny Bright, waving banners including a mock Tui billboard: "John Key's not looking after his own, and his corporate mates' interests - he's looking after the public.

Mr Key will address the conference tomorrow afternoon.
