New Zealand captain Ross Taylor elected to field after winning the toss against Sri Lanka in the fifth and final one-day international in Hambantota on Monday.
Sri Lanka, who have already gained an unassailable 3-0 lead in the five-match series, brought in paceman Shaminda Eranga and debutant spinner Akila Dananjaya in place of Nuwan Kulasekara and Rangana Herath. New Zealand retained the side.
The opening one-dayer was called off without a ball being bowled due to rain.
