The New Zealand under 20 rugby coach Dave Rennie has made nine changes to the side that beat Fiji 44-11 last week for the Baby Blacks second match of the Junior World Championship against Samoa in Argentina.
The defending champions New Zealand face the Samoans in Santa Fe this morning and Rennie promised that all the squad would get in run in the opening two matches.
He's guided the Baby Blacks to 11 consecutive victories in the Junior World Championship, and despite a 33 point win over Fiji, he says there are still areas the champions need to improve.
Rennie says the teams defence needs work, as does the kick chase and ball retention.
New Zealand's final pool match is against Wales on Monday.
