The Reserve Bank of New Zealand (RBNZ) has published its review of insurers’ solvency returns for the 2015 financial year.

Insurers generally reported a solvency position at or above their target, it says.

General insurers had a solvency ratio of 142% and solvency margin of $NZ702.3 million ($672.35 million).

The few insurers that recorded substantial losses made “a significant capital injection to restore their solvency position”, the review says.

“While it is good that this has occurred, it is of some concern that some insurers appear to rely upon ‘just in time’ parental capital injections rather than having a suitable buffer above solvency requirements to manage adverse experience.”

The paper does not name the insurers that were in the red, nor list the 35 general insurers that featured in the review. Overall, regulatory solvency returns provided to the regulator came from 62 licensed insurers that are subject to the country’s six standards in effect.
