The Koreans, two places behind New Zealand at No8 in the world, play a fast-breaking game and are happy on the counter attack.
New Zealand have shown a welcome resolve when scrambling in defence, they work the flanks well, can be patient and can string together phases of passing.
They also have strikers such as Hugo Inglis and Stephen Jenness to cause problems for the opposing defence.
The squad for the World League 3 tournament in Rotterdam from June 13 to 23 - effectively the semifinal for the final in Delhi next January - will be named after the Korean series.
The New Zealand squad contains 11 players with fewer than 20 international caps. That's balanced by the likes of captain Dean Couzins, with 276 caps, striker Phil Burrows, on 292, and defender Shea McAleese on 175.
"In an ideal world you get more out of tournament situations. That's where the big things happen, like Olympics and World Cups," Auckland defender Couzins said. "You know what you're going to get [from the opponent]. As long as you keep growing your game you can get a lot out of it."
Penalty corner exponent Andy Hayward shares Couzins' view.
"Come Rotterdam it will be more about the other teams."
