A rollicking maiden century by Sri Lanka's Thisara Perera was ultimately in vain as New Zealand wrapped up the one-day series with a 21-run victory in the second ODI at Mount Maunganui.

With Sri Lanka chasing New Zealand's 319 for seven, they were on the ropes at 128 for seven when Perera opened up. He faced 74 deliveries and cracked 13 sixes and eight fours before he was the last wicket to fall and Sri Lanka were out for 298 with 22 balls remaining. Sri Lanka reached 112 for two when Ish Sodhi captured the wicket of Kusal Mendis for 20 to trigger a collapse which saw five wickets fall in six overs.
