Also tagging along was Jasmin Kolasinac, who was part of the Serbian national side which won the European under-17 championships last year.
Kolasinac (17) displayed the skills which has seen him land a scholarship to Wagner College in New York next year.
He was spending a year in New Zealand learning English and attending King's College.
Floerchinger, who also teaches at King's College in Auckland, said there was plenty of young water polo talent throughout the country.
''There has always been plenty of kids playing the sport, in whatever form. But for the teams and players to improve they need to see the speed, the pace and the class that the Europeans have,'' Floerchinger said.
''Now we can't send everyone to Europe, but what we can do is being someone here like Jasmin, who was playing in the first division for Serbia when he was 17. He's been playing the game since he was 6.''
Kolasinac would help lift the standard of water polo in New Zealand. Water polo in Serbia was the equivalent of rugby in New Zealand.
Floerchinger said everyone had to row in the same direction in all minority sports and water polo was no different.
Water polo had the advantage of being very popular with youngsters.
''There are more people playing some form of water polo in New Zealand than there are playing rugby league. So we have the numbers coming through.''
He said coach education was important in the sport and it was on the improve.
