Alastair Cook and Samit Patel hit unbeaten centuries as England began the Super League phase of the Under-19 World Cup with a convincing win.
They beat New Zealand by 97 runs after skipper Cook (108) and Patel (102) put on 164 to see England to 306-5.
Cook struck 11 fours during his innings, one fewer than Patel, who faced only 90 deliveries.
New Zealand could only muster 209 all out in reply as Tim Bresnan and Luke Wright took two wickets each.
"We have always said that it is up to one of the top order to bat through and today that was me," said Cook.
"I am pleased to get some runs and it's obviously good to start the Super League with a win.
"Samit's innings was something special, it was a pleasure to be at the other end to watch it."
Pakistan remain the only unbeaten team in the tournament after cruising to a nine-wicket victory over Zimbabwe.
Khaleed Latif guided Pakistan to their victory target
Off-spinner Tariq Mahmood took 4-33 as Zimbabwe were dismissed for just 141 and Pakistan knocked off the runs with 20 overs to spare.
Skipper Khaleed Latif hammered a six and 12 fours in his 84 not out and manager Sultan Rana afterwards hailed a "very good all-round team effort".
Eoin Morgan scored 117 as Ireland outplayed Uganda by 123 runs in their opening Plate Championship game.
The Irish piled up 329-9 in their 50 overs with 17-year-old Morgan's third-wicket stand of 166 with Kevin O'Brien, who made 70, providing the foundation.
"The wicket was very good and the conditions were ideal with the ball really coming onto the bat," said Morgan.
He underlined his all-round ability by taking two wickets before Uganda had scored and Greg Thompson (2-22) and Boyd Rankin (2-43) hastened their decline to 206 all out.
Hosts Bangladesh cheered a 4,000 crowd at Chittagong as they defeated Canada by four wickets.
The manner of their win was unconvincing, however as careless shots gifted wickets to Canada, who had earlier been dismissed for 136.
Bangladesh were in trouble at 103-6 but 27 not out by Nazim Uddin saw them home in the 35th over.
