The Earthquake Commission's reinsurance premiums have more than tripled since the Christchurch earthquakes, leaving the Crown vulnerable to a big bill if the country's hit by another major event.
The government-backed natural disaster insurer is paying annual reinsurance premiums of $140 million, up from about $39 million before the spate of Canterbury quakes. Premiums now have to be reviewed annually as opposed to every three years, chairman Michael Wintringham told Parliament's finance and expenditure committee.
The new deal lifted EQC's cover to $3.25 billion from $2.5 billion previously, and raised the excess to $1.75 billion from $1.5 billion.
"The price we are paying for our cover at the moment reflects the uncertainty of the Christchurch events, and the longer we go on without another one, the memory of the market fades," Wintringham said.
The government has opted for cover where it pays the first $1.75 billion and anything beyond $5 billion in a major earthquake, with Wellington still seen as the most likely candidate. The Crown's insurance liability for EQC property damage was $8.33 billion as at Oct. 31, and $1.96 billion for the former AMI it took on, according to Crown accounts published today.
