De Villiers, Duminy See South Africa Home
South Africa 236-4 (de Villiers 89no) beat
New Zealand 230 (Ronchi 99) by six wickets
First One-Day International, Tauranga
De Villiers hit 89 and Duminy 50 as the tourists overhauled a target of 231 in 48.1 overs.
Luke Ronchi had earlier fallen for 99 as New Zealand were all out for 230 in 45.1 overs.
Ronchi combined with Trent Boult (21 not out) to help the home side recover from 156 for nine, adding 74 for the final wicket.
However, despite South Africa making a slow start, and slipping to 97 for four, an unbroken 139-run stand between de Villiers and Duminy completed their victory.
Morne Morkel, Vernon Philander, Imran Tahir and Ryan McLaren all took two wickets as Dale Steyn and Duminy took one apiece as South Africa, who won the toss and chose to bowl first, produced a fine all-round display.
However, after the top order had come and gone with nobody bettering Tom Latham's 26, Ronchi gave the innings some respectability with a superb innings of 99 in 83 balls.
He turned down an easy single that would have taken him to a century only to fall to Steyn as he tried to extend New Zealand's innings as long as he could.
Boult backed up his batting with the early wickets of Quinton de Kock (9) and Faf du Plessis (8) before Hashim Amla and Rilee Rossouw began the recovery.
Amla hit 38 in 74 balls and Rossouw 26 in 31 but their dismissals, by Kyle Mills and Corey Anderson respectively, opened the game up once again.
De Villiers then hit 89 in 85 balls with nine fours, and Duminy cracked 50 in 72, with three fours and two sixes - including the winning hit off Mills - to put the away side 1-0 up in the three-match series.
The second game is at the same venue on 24th October.
