The Irish made history on 5 November with a first ever win over the world champions in Chicago and Schmidt knows the All Blacks will want revenge.
"I think they'll come full-strength, fully loaded. Maybe we surprised them a little bit last week," said Schmidt.
Ireland made a full 15 changes for Saturday's 52-21 victory over the  world's 18th-ranked side Canada.
Schmidt will recall all his big guns for the rematch at the Aviva Stadium, while the visitors are expected to be far stronger too.
Steve Hansen's back-to-back world champions were hampered by a string of second-row injury problems at Soldier Field, but will have lock Brodie Retallick back in his unique auxiliary playmaker role in Dublin.
Despite Ireland ending New Zealand's record 18-match winning sequence in Chicago, most neutrals will expect the All Blacks to assert their authority with victory.
New Zealand reacted to their shock loss by running in 10 tries in beating Italy 68-10 on Saturday.
South Africa were the last team to beat New Zealand in successive encounters, back in 2009, further emphasising the scale of Ireland's challenge.
"I read that they didn't really look back too much at the defeat to us before playing Italy this weekend," added Schmidt.
"Well they have that game done and now they will look at us over the next few days, and they'll have a really good plan.
"They are extremely well coached and incredibly well prepared physically, and I think the rate they play at if they have the ball, you're under pressure if they've got it.
"And I think they'll have more access to it if they've got their second row back."

He was speaking in an emergency debate at the European Parliament in the wake of last week's EU referendum.
The UK voted by 52% to 48% to leave the union after 43 years of membership.
Mr Smith used his speech in Brussels to urge the EU to respect the will of Scotland after its electors voted by 62% to 38% to remain in the EU.
He won applause form the chamber when he said he was "proudly Scottish and proudly European".
Mr Smith went on to say: "I want my country to be internationalist, cooperative, ecological, fair, European.
"And the people of Scotland, along with the people of Northern Ireland and the people of London, and lots and lots of people in Wales and England also, voted to remain within our family of nations.
"I demand that that status and that esprit European be respected.
"But colleagues, there are a lot of things to be negotiated.  We will need cool heads and warm hearts. But please, remember this: Scotland, did not let you down.
"Please, I beg you, chers collÃ¨gues, do not let Scotland down now."
After his short address he received a standing ovation. The leader of UKIP and pro-Leave backer Nigel Farage did not join in the applause.
MEP Mr Farage had earlier spoken to his fellow EU parliament colleagues.
He told them that "the little people" had rejected "big politics" in order "to get their country back".
Mr Farage believed the UK now offered "a beacon of hope" across Europe for other countries that wanted to leave the EU.
He said:  "When I came here 17 years ago and said I wanted to lead a campaign to get Britain to leave the European Union, you all laughed at me. Well, I have to say, you're not laughing now are you?"
Coach Joe Schmidt believes Ireland will face a furious backlash from a fired-up New Zealand side in Dublin on Saturday.
