World and Olympic champions Belgium were struggling to break the deadlock against South Korea with the half-time score reading 0-0.

But one minute into the second half, a penalty corner from Alexander Hendrickx saw Belgium take the lead.

That was the start of a dominating performance with four more goals coming from Tanguy Cosyns, Florent van Aubel, Sebastien Dockier and Arthur de Sloover in the final 16 minutes.

The New Zealand game saw a faster start as they put three past World Cup debutants Chile in the first 20 minutes.

Sam Lane got one and Sam Hiha scored twice as the Kiwis heav-pressure technique worked wonders.

While the South Americans were more composed in the second half, they could not find the firepower on the other end of the field.

But a consolation arrived finally as Ignacio Contardo controlled a long ball before beating 3 defenders and score the first men’s World Cup goal for the nation.

The Netherlands took 20 minutes to get their first goal against Malaysia, with Thijs van Dam puncing on a loose ball.

The Dutch doubled their lead thanks to Jip Janssen, who made no mistake from a penalty stroke four minutes later.

Teun Beins and Jorrit Croon helped them to a comprehensive 4-0 win to start their campaign.

Germany recorded a one-sided 3-0 win over Japan but the Asian side did frustrate the two-time champions in the first half.

But they were not able to keep the intensity for long as captain Mats Grambusch put the Germans in front.

A brilliant counter-attacking move resulted in the second goal for Germany as Christopher Rühr rounded the keeper for a clean finish.

Thies Prinz scored the final goal in the 49th minute to seal the victory.
