New Zealand have made 10 changes for their final Tri-Nations match against South Africa in Rustenburg on Saturday.
Howlett switches from his usual position on the wing to full-back
Only captain Richie McCaw, Ali Williams, Dan Carter, Mils Muliaina and Sitiveni Sivivatu remain from the 45-26 victory over the Boks last weekend.
The All Blacks will field a potent back three as Doug Howlett comes in at full-back, while Joe Rokocoko partners cousin Sivivatu on the wings.
Hooker Keven Mealamu and scrum-half Piri Weepu have both been rested.
All Blacks coach Graham Henry said their replacements, Andrew Hore and Jimmy Cowan, deserved their chance to shine.
"They've both been great team men and have played well from the bench. They have earned their opportunity," said Henry.
"Doug Howlett has played at fullback for Auckland, the Blues and the All Blacks - it's an exciting combination to have him alongside Joe Rokocoko and Sitiveni Sivivatu."
New Zealand: Doug Howlett; Joe Rokocoko, Mils Muliaina, Aaron Mauger, Sitiveni Sivivatu; Dan Carter, Jimmy Cowan; Tony Woodcock, Andrew Hore, Carl Hayman, Chris Jack, Ali Williams, Jerry Collins, Richie McCaw, Rodney So'oialo.
Replacements: Anton Oliver, Neemia Tialata, Jason Eaton, Marty Holah, Byron Kelleher, Luke McAlister, Rico Gear.
