Launceston captain Tom Rawlings believes experience was vital in the 35-22 win over lowly Bournemouth.
After trailing for long periods, 12 unanswered points late on secured the All Blacks' victory.
"They ran us very very close but I think experience kicked in and helped us pull through," Rawlings told BBC Radio Cornwall.
"It was a bit flat on the field and in the changing rooms and something wasn't quite clicking."
Thomas Vaughan-Edwards went over early on and Daniel Pollard added a penalty for Bournemouth, while a hat-trick of penalties from Kieron Lewitt brought the All Blacks to within one point.
The hosts' Liam Yeo and visitors' Scott Chislett then traded tries to leave the home side 16-15 in front at the break.
Sam Hardcastle restored Bournemouth's lead when he crossed early in the second half, but the game changed when Vaughan-Edwards was sent off.
Two Lewis Paterson tries either side of a Josh Lord score rounded off the scoring and secured the points for Rawlings' men.
"We were the dominant team even though they gave us a good game," Rawlings added.
"For some reason we didn't adapt our game to stop them and break them down.
"We've got a funny fixture next week in Barking and they'll fight to the bitter end as all teams at the bottom will."
