Otago will power up with Bower.
All Blacks prop George Bower has been released from national duties and will be on the bench this weekend.
The loosehead replaces Ben Lopas and is one of 16 All Blacks given the green light to play in the fifth round of the NPC.
Otago travel to Nelson to play Tasman on Saturday night. Both teams have three wins from four games and are ensconced in the top four.
Otago have made just one other change.
Highlanders loose forward Oliver Haig will start at blindside in place of the hard-working Will Stodart, who drops to the bench.
Stodart has had a heavy workload during the first four rounds. He made 17 tackles and teamed up with Lucas Casey (18) and Christian Lio-Willie (17) in the 33-19 win over Counties-Manukau at Forsyth Barr Stadium.
Haig missed round one with an ankle issue and came off the bench in the next three games.
Tasman will have the services of All Blacks midfielder Timoci Tavatavanawai.
The Highlanders co-captain was named the player of the year for the club following an outstanding season.
He goes by the nickname "Jimmy the Difference" and will pose some serious defensive issues for Otago, who have had to do a lot of defending in their first four rounds.
They have demonstrated considerable resolve in that department. But the game plan will be to cut off the supply of ball for Tasman’s exciting backline.
Tasman winger Macca Springer has collected five tries, made nine clean breaks, beaten 17 defenders and run for 302m.
When you add all that up, there is a compelling case for arguing he is one of the more potent wingers in the competition.
And he is just one of many threats out wide.
The Mako were humbled 37-7 by Bay of Plenty in the opening round. But since then, they have strung together healthy wins against Manawatū (49-17), Northland (28-14) and North Harbour (43-19).
Wellington and Waikato are the big winners from the decision to release the All Blacks.
Kyle Preston, Peter Lakai, Ruben Love and Asafo Aumua will line up for the Lions against Auckland in Porirua on Sunday, and Waikato get the services of Anton Lienert-Brown, Luke Jacobson, Samipeni Finau and Ollie Norris for their Ranfurly Shield defence against Southland on the same day.
