World No 6 New Zealand had drawn 3-3 with the Dutch in pool play, which added to Batch's disappointment at the outcome of Sunday night's decider. A win would have got them to The Hague.
That said, he saw good signs out of the tournament, particularly a resolute defensive operation.
"We've shown that resilience a number of times in matches; it's becoming something of a trademark for us and that's a very good sign," Batch said. "Overall I'm pleased with the progress we've made.
"The players have developed well. The number of field goals we've scored was very pleasing."
World No 9 Belgium caused a boilover in the final.
Having beaten New Zealand in the semifinal, they defeated Australia 7-6 in a penalty shootout after the scores were locked 2-2. It is Belgium's first win at a top-level international tournament.
Both New Zealand teams are through to the World League finals in Tucuman, Argentina (women, December) and Delhi (men, February). The World Cup is where they want to be, which puts the heat on in Stratford in October, where the continental champion will be assured of a spot.
