NELSON: Sri Lanka won the toss and put New Zealand into bat in the rain-delayed fourth one-day international at Saxton Oval in Nelson on Saturday.
The match has been reduced to 24 overs each after a lengthy delay because of the weather.
With the Duckworth-Lewis system likely to have a bearing on the outcome, Sri Lanka captain Angelo Mathews said bowling first was the only option.
Sri Lanka have made one change from the side that won the third match by eight wickets with Thisara Perera coming in for Nuwan Pradeep.
New Zealand, who lead the five-match series 2-1, have made two changes with Matt Henry returning for injured quick bowler Tim Southee and spinner Ish Sodhi replacing Doug Bracewell.
Kane Williamson again leads the side while regular captain Brendon McCullum is sidelined with a sore back.

New Zealand: Martin Guptill, Tom Latham, Kane Williamson (captain), Ross Taylor, Henry Nicholls, Mitchell Santner, Luke Ronchi, Adam Milne, Ish Sodhi, Matt Henry, Mitchell McClenaghan.
