Police said the men were aged in the 30s and 40s and were from the same family.
The two bodies were recovered from the Manawatū River on Sunday afternoon.
Police received reports just after 5.30pm on Sunday that two men who were swimming in the river near Awapuni were missing.
Searchers recovered the men’s bodies a short time later at a nearby location just before dark.
Police are making enquires in relation to the deaths on behalf of the coroner, who will release their findings in due course.
