NRMA home insurance holders have been warned to expect a "slight" increase in their premiums if they claimed on damage caused when tornadoes ripped through the Kiama area in February this year.
An NRMA spokeswoman said the increase would be a result of a change in the residents' no- claim bonus status.
"Until their next renewal is calculated, we cannot determine what effect this will have," the spokeswoman said.
"This is outlined in our product disclosure statements as well as in an individual's certificate of insurance."
Kiama and surrounding suburbs were declared a natural disaster area when a family of tornadoes brought winds of up to 250km/h and caused millions of dollars worth of damage in late February.
The NRMA spokeswoman said no pricing changes for Kiama had been implemented in response to the disaster, so those who hadn't claimed would not be affected.
"This applies to all insurance we provide for Kiama residents, including home, motor or caravan insurance," she said.
Meantime, Kiama Municipal Council has announced its damaged leisure centre will reopen on September 28. A council spokeswoman said full repair costs would be available once the facility was operating again.
