NASA has dropped the call to its supporters to hang around polling stations after they cast their ballot on Tuesday.
Leaders Raila Odinga and Kalonzo Musyoka asked their backers to go home after voting to avert a clash with the police.
This emerged in Kisumu during a rally also attended by co-principals Musalia Mudavadi and Moses Wetang'ula.
Kalonzo said a situation where people mill around voting centres might create chaotic scenes which might end up making people shun polling stations.
This is a deviation from an earlier plan where the National Super Alliance leader asked supporters to 'guard their votes' under the adopt-a-polling station strategy.
The move was opposed by security agencies led by Interior CS Fred Matiang'i and the Independent Electoral and Boundaries Commission.
IEBC maintained that voters must be at least 400 metres away from the polling station after they cast their ballot.
The commission said only accredited agents, journalists, and poll officials will be allowed at the stations.
On Thursday, Raila told his supporters in Kisumu that they will not stop at anything to ensure people turn out in large numbers to vote.
He asked the lot to instead go and mobilise those who have not cast their ballot to take part in the election.
Kalonzo said the new strategy is meant to ensure their supporters are safe adding that they have information authorities could harm those found hanging around polling centers.
"Jubilee is planning to use police to teargas opposition supporters to bar them from voting. Vote and wait for results outside the polling stations or at home."
Kalonzo urged NASA supporters to obey the 400-metre polling station cordon as directed.
"We are aware they are planning to create tension in opposition strongholds so that they can teargas our supporters," Kalonzo said.

However, he reiterated that the adopt-a-polling station committee should be at the voting centres to ensure eligible voters cast their ballot.
"This is the time and best opportunity to bring the desired change Kenyans are yearning for. We have to vote as has never been seen before to achieve our goal."
The principals said every vote counts and therefore, urged supporters to target 100 per cent turnout next week.
Raila told his supporters not to fear police presence at the polling stations adding that citizens are determined and yearning for change.
"The dream of many Kenyans who want change shall come true next Tuesday. The resolve to send Jubilee home cannot be defeated," he added.
"I can assure you, my fellow citizens, that the change you have been waiting for is just a few hours away. Let us stand firm and come out and vote."
The group is centering their campaigns on their desire to improve standards of living, curb corruption in government and improve government services.
Raila promised to immediately address the soaring prices of basic commodities such as maize flour, sugar, milk, and fuel among others if elected president.
He faulted President Uhuru Kenyatta and DP William Ruto for presiding over massive corruption saying it was to blame for the high rate of inflation.
"On matters corruption, Kenya is playing in the league of countries such Bangladesh, Cameroon, Gambia, Madagascar, and Nicaragua," he added.
The team said the death of IEBC ICT manager Chris Msando and businessman Jacob Juma are among cases of rampant extrajudicial killings in the country.
"Those who killed Msando are the same people who murdered Juma. Such killings will never be witnessed under Nasa government," Kalonzo said.
Wetang’ula said Kenyans will not accept any rigged election like they did in March 2013.
"Uhuru and Ruto have failed to deliver on the 2013 pledges to Kenyans and have now resorted to unconstitutional activities. We must stop them," the legislator said.
"We want to show Jubilee how to govern the country. Kenyans are tired of hardships. Raila has the capacity to transform the country.
Mudavadi said Kenyans must make NASA exodus to a new dawn complete by voting to Raila to the last man.
He assured that Raila’s presidency will protect every citizen irrespective of party affiliation or region they come from.
"He is a democratic leader and his government will guarantee safety to every citizen," Mudavadi said.
The ANC leader said they will emerge victorious next Tuesday. "We are winning, we shall win …we cannot lose."
