While Oberrender was under repair, CortDiv69 was attached to Task Force 79 of the Seventh Fleet.
Following the completion of repairs, she went to Borgen Bay off Cape Gloucester for an anti-submarine patrol in early December.
Returning to Seeadler Harbor on 11 December as part of the screen for Task Group 79.4, the destroyer escort conducted gunnery training there and en route to the Huon Gulf, where she patrolled from 18 December.
With Task Group 79.2, Oberrender returned to Seeadler Harbor on 21 December, remaining there until the last day of the year, when she departed for the invasion of Lingayen Gulf as part of the screen for the task group.
Again without result, she engaged a Mitsubishi A6M Zero attacking a convoy of transports.

Taking up duty on an anti-submarine patrol station in Lingayen Gulf between 9 and 12 January, Oberrender escaped the notice of Japanese kamikaze pilots, whose attacks damaged LeRay Wilson and the destroyer escort Gilligan, also on the patrol line.
At the end of this period, she departed with Gilligan and the destroyer escort Richard W. Suesens for San Pedro Bay.
The three escorts acted as part of the screen for the Landing Ship, Tanks of Task Forces 78 and 79 until arrival at the bay on 17 January.
On the next day, Oberrender left for Hollandia, Netherlands New Guinea, as part of the screen for two divisions of attack cargo ships, part of Task Group 78.6.
The task group was diverted to Biak en route and after arrival there, she anchored at nearby Mios Woendi Lagoon until 27 January, when she began a three-day patrol off Biak before returning to Mios Woendi.

Oberrender became part of the screen for the task group, known as the Third Lingayen Reinforcement Group, on 1 February.
The latter departed from Biak with its transports carrying the 41st Infantry Division two days later, and she continued screening the task group, which unloaded its troops at Mangarin Bay on Mindoro on 9 February.
After the unloading, the task group and its screen continued to San Pedro Bay, where it dissolved on 12 February, leaving Oberrender at anchor awaiting a new assignment.
Three days later, she departed for Ulithi in the Caroline Islands, as part of the screen for attack transports of Task Group 78.5; the ship arrived there on 19 February and remained anchored there until 2 March, when she participated in anti-submarine training with the submarine Skipjack.

Oberrender departed Ulithi on the next day, acting as part of the screen for three fleet oilers on their voyage to the Tarraguna Anchorage near San Pedro Bay, which was reached on 7 March.
Anchored in the bay for several days, she became part of Task Group 51.1 in preparation for the invasion of Okinawa, and on 10 March participated in anti-aircraft firing exercises.
With the task group, the ship conducted rehearsals for the landings in Leyte Gulf between 14 and 16 March, then returned to the anchorage.
