''It would have been nice (to have scored) with 30 seconds to go," Child quipped.
''There were still a couple of hairy moments at the end.
''That was a huge game for us. We knew before the tournament it was a clutch game and we're really pleased to overcome that hurdle."
It was Child's second goal of the tournament, and kept up a rich vein of form, but the win was built on a solid defensive operation in the first half, during which fifth-ranked England put the heat on the Black Sticks.
Goalkeeper Devon Manchester was in assertive form and captain Dean Couzins marshalled a conscientious defensive effort, making an important block and clearance on the Black Sticks line as England pressed hard in the second half.
Andy Hayward's penalty stroke, awarded when Blair Hilton was pushed in the back, put New Zealand ahead midway through the second half; Adam Dixon had England level with 12 minutes to go before Child's late intervention.
''England are a very good team and we've had some pretty even battles with them in recent years so it was good to poke one in at the end and get one over them," Child said
.
New Zealand's tactic of pushing England's attack wide paid a dividend. Child pointed to the strength of their midfielders working down the centre of the pitch.
''It's much easier to defend there, so credit to the guys for sticking to the game plan for 70 minutes."
New Zealand had talked about the last time they played their third game in a major tournament, when they lost 3-1 to Argentina at the World Cup in The Hague in June.
It was a poor performance and one they were not keen on repeating at the same stage of the Games event.
''We talked about doing well in these crunch games," coach Colin Batch said.
''There's a lot of belief in this group and that'll give us confidence."
New Zealand will ensure their feet are firmly planted for the Malaysian game. They can't afford any slipups after having toiled hard to open a door to the final.
''This team is building and building," Child said.
''I think we'll get to the gold medal match, but we're not looking any further than the next game. We'll make sure we don't get stuck in the clouds."
