The 2012 team performance ranks as the fourth-best effort by a New Zealand team since the event began at the Geneva Golf Club in 1964.
New Zealand has finished runner- up twice in the World Amateur Team's Championship in 1982 in Switzerland and in 1990 when they were hosts at the Russley Golf Club.
Ko carded rounds of 70, 69, 67 and 68 for a 14-under par total to finish as the leading individual, six shots ahead of Krista Bakker (Finland) and Camilla Hedberg (Spain).
She was the first New Zealand woman to finish as the leading individual at the World Amateur Team's Championship and followed in Phil Tataurangi's footsteps, who achieved that feat in Canada in 1992.
The teenage superstar was also awarded the Mark H McCormack medal at the prizegiving for being the game's outstanding amateur in 2012.
Ko became the first woman to receive the award for the second year running.
"It is really special to win this award again," said the 15-year-old.
"I have never lost the World No1 ranking since I got it last year and I am very proud of that achievement."
The men's Eisenhower Trophy begins in Turkey this week with Ben Campbell (Masterton), Vaughan McCall (Gore) and Mathew Perry (Hamilton) looking to emulate the feats of the 1992 team, who famously won the title in Canada.
