Kaiser Permanente Hawaii has acquired 6.2 acres under its Wailuku Medical Office for $22 million.

The state’s largest health maintenance organization — both a medical provider and health insurer with more than 255,000 members statewide — said the investment “allows for greater flexibility and certainty around future operational costs.”

Kaiser has operated the Wailuku Clinic since 1983 and provides specialty care to more than 58,700 members.

The company said it is considering future renovation and expansion of serv­ices at the clinic.

A company spokeswoman said there are no specific plans for expansion at this time.

The HMO assumed control of three Maui County hospitals on July 1 in the largest privatization in state history.

The HMO pledged to inject more resources into Maui Memorial Medical Center, Kula Hospital & Clinic and Lanai Community Hospital, the only acute-care facilities for about 200,000 residents and visitors in Maui County.

Following the transition, the company said it would invest more than $50 million to expand services and update technology to improve patient care.

More rain, humidity expected

The National Weather Service says humid conditions are expected to continue through today as a front approaches from the west. The front will then move slowly down the island chain tonight and Friday before stalling over the central or eastern islands over the weekend into early next week.

Trade winds and less-humid weather are expected to return by the weekend, but more unsettled weather is expected early next week.
