ACC is looking to tighten up on the medical certification process as the average time off work for those injured increases. It's seeking to award prototype agreements to organisations with what it calls "a substantial reach into primary care"  who have robust proposals for delivering effective improvements.  

In the last financial year, Accident Compensation Corporation covered more than  $2bn new injury claims and paid for  $5bn dollars' worth of treatment and rehabilitation services. In its annual report, released in the last few days, ACC cites improving rehabilitation and building financial resilience as its top priorities. No one from the Corporation  was free to come on at this time, but in a statement it says with the current tender, ACC is aiming to ensure that certification more accurately reflects the individual's injury and recovery potential.

But how do GPs feel about this move to involve others in the process? Angus Chambers is Chair of GenPro - the organisation representating general practice and urgent care - he is also GP in Riccarton in Christchurch
