Ok that aside, I found some figures.
In ACC's Injury Statistics 2008 report (http://tr.im/BV1k) ACC details claims against the Motor Vehicles account - the virtual pool that gets claimed upon whenever a road-registered vehicle is involved in an accident. The report gives statistics for the number of new claims, the number of active claims and the cost of those claims. As the report breaks down the claims by vehicle type, it's easy to compare the cost of claims:
Cyclists:
- 567 active claims
- $12,573,000
- $22,174 per claim
Pedestrians:
- 1115 active claims
- $24,494,000
- $21,967 per claim
Car Occupants:
- 8525 active claims
- $208,305,000
- $24,434 per claim
Motorcyclists:
- 3173 active claims
- $62,523,000
- $19,704 per claim
