President Hernández has been heavily criticised by the opposition for standing for a second term even though re-election was prohibited under the Honduran constitution, until a 2015 Supreme Court ruling overturned the ban.
Shortly before the electoral tribunal announced the partial results, President Hernández told cheering supporters that he was certain of victory.
He was joined by the crowds in shouts of "Four more years!"
Mr Nasralla was equally confident of victory even before the partial results were made public, telling his backers "We are winning!".
Six million voters have taken part in the vote, in which members of congress and mayors are also elected.
Mr Hernández has been credited with lowering the murder rate in one of the world's most violent countries.
He also conducted a purge against corrupt police officers and created a new militarised police force.
Revamped new maximum-security prisons have helped the government regain control over some jails from inmates.
But the opposition has linked Mr Hernández with a huge scandal, alleging that social security funds had gone into his 2013 presidential campaign.
They also say his government has become increasingly authoritarian, with a new anti-terrorism law making it a crime to march in protest.
