Heartland 15 rugby coach Ross Cooper has made three changes and two positional switches for his side's match against Argentina A in Rosario on Sunday (NZT).
Wairarapa-Bush loose forward Sam Henderson comes in at No 6, Wanganui's Logan Vaughan takes over at centre and North Otago's Scott Mayhewwill start the match on the right wing.
In positional switches, King Country's Aarin Dunster moves from No 6 to lock and North Otago's Karne Kaufana switches from centre to second five-eighth.
The match is the last of the team's three-match tour of Argentina.
They had opened with a 23-22 win over Salta Province but lost 13-35 to Tucuman Province.
Cooper said today the team were determined to finish the tour on a winning note after the loss against Tucuman.
"This match presents a very exciting challenge for us.
"The local conditions are foreign to our players - it is very warm and the kickoff has been pushed back to 8.30pm because of the heat.
"We've also eased up on training to allow the players to freshen up.
"We expect a torrid battle up front, especially as Argentina A will be selected largely from the very top sides in the local provincial competition.
"However, in both of our previous games our pack has matched up well," Cooper said.
Cooper said the team had made great strides on tour.
"We will have to play extremely well to win, but the team will be well prepared and motivated.
"This is an international and that is how we are approaching it.
"It's a rare honour to wear the black jersey against another country, especially for these Heartland players, and I know the guys are determined to play well."
