De Villiers had preached a desire to have done th basics well by the end of the tour.
''We're not far off, and the basics we did do well, certainly better than New Zealand in this tour.
''That gives us lots of confidence but it's a matter of being more ruthless in certain ares of the game," he added.
South Africa begin their bid for a first World Cup title at Hamilton against Zimbabwe on February 15, so although the game was curtailed he felt it was important the players who had not been there before got a look at the surroundings.
''I'm not huge on 'oh this is the way the wicket is going to play when we come back for the World Cup'," he said.
''No two wickets are the same and it was important for us to acclimatize to the surroundings. Even though New Zealand is similar to South Africa in the way people do things here, theer are a few little things different and it's important to me the boys experienced it so it's not a whole new different thing when we come over to the World Cup."
De Villiers, ranked the world's No 1 ODI batsman, wasn't about to give New Zealand a kicking as he prepared to leave the country either. He knows this is an unusually early start to the season for the hosts, and they were seriously short of match play.
''New Zealand are very competitive. It's obvious they didn't have the best of series now but by no means does that tell me what we can expect in the World Cup.
''We know they are a team for the big moments, they're always competitive in the field with bat and ball.
''This has been a nice run in for us, but it doesn't mean it will be okay at the cup. We know we are going to have to graft hard again."
South Africa fly to Australia for a T20 series and five further ODIs, while New Zealand depart for the United Arab Emirates on Thursday for three tests against Pakistan and five ODIs.
