Central Solomons - New Georgia, 30 Jun 1943 - 27 Oct 1943 
After Japanese ground forces abandoned Guadalcanal in early February 1943, Japanese aircraft continued air attacks, using a forward air base completed in December 1942 at Munda on New Georgia Island. ​

I don't summarize the long and complex New Georgia Campaign, which also included the capture of both Rendova and Villa Lavella, an island just north of Kolombangara.

Several naval battles accompanied the New Georgia Campaign, and are mentioned in the Solomons Sea War webpage.
