Korea have beaten the Black Sticks men 4-3 today in the deciding match of their five test series at Lloyd Elsmore Hockey Stadium in Pakuranga, Auckland.
Following two Black Sticks victories last weekend, Korea won the third and fourth tests to leave it all square going into today's final test of the series.
Black Sticks captain Dean Couzins said his team's error rate was the difference between the two sides today.
"With a lack of basic skills you can't impose yourself on a game. You start to build a bit and then you're making too many errors. It's the taking two steps forward and one back scenario."
Despite the series loss, Couzins felt they were still on track for the London Olympics.
