The opposition withdrawal from runoffs in the constituencies where candidates failed to win at least 50 percent of the vote left the NDP with 383 hopefuls standing mostly against members of the same party for 283 seats.
Polling stations closed at 7:00 pm (1700 GMT) with the results expected by Wednesday.
"The NDP is guaranteed a 97 percent majority in the next parliament," proclaimed the government daily Al-Ahram on its website.
The prospects for political change took a heavy blow when Egypt's only serious opposition, the Muslim Brotherhood, failed to win a single seat in the first round, while the NDP, which has dominated parliament for 30 years, won 209 out of 221 seats.
Egypt's two main opposition blocs, the Brotherhood and the liberal Wafd party, decided to boycott the runoff after official results from the first round were announced, citing violence, intimidation and fraud.
Army trucks deployed on Sunday near polling stations in some parts of Cairo, and heavily armed riot police were also on alert.
Police arrested more than 1,000 Brotherhood supporters before the first round, and at least 11 were later given two-year jail terms for distributing its campaign literature.
The conduct of the election drew criticism from human rights groups and also from the United States, Egypt's key ally.
The Brotherhood, which held a fifth of seats in the outgoing parliament of 508 elected MPs after Egypt's last election in 2005, fields its candidates as independents to skirt a ban on religious parties.
Its decision to withdraw its remaining 27 candidates from the second round marked its first boycott of an election since the 1990s.
The Wafd, which usually has working ties with the government, won two seats in the first round, but also decided to pull out of Sunday's runoff in a rare display of resolve for the fractured party.
Three other parties which each won a seat last week decided to stay in the race.
According to Egypt's electoral commission, 167 independent candidates were also on the ballot on Sunday, but that figure included the Brotherhood members.
"The NDP are dictators. But change is possible," said Mohammed Magdi, 27, who planned to vote for an independent standing against the NDP incumbent in a poor part of east Cairo's Matariya district.
"Look at this school!" he said, pointing to the shabby buildings around the school being used as a polling station. "Is it good? Look at the road outside. Is it good?"
Analysts said the NDP appeared to have overplayed its hand by virtually wiping out the opposition, strengthening the impression of a one-party state in an Arab country which Mubarak has ruled for the past three decades.
"The pullout of the opposition adds to the legitimacy crisis. It means the opposition are no longer buying into the system. The damage done to the NDP is huge," said Amr Hamzawi of the Carnegie Endowment for International Peace.
International watchdogs and independent Egyptian observers reported widespread violence, vote-rigging and intimidation of opposition candidates in the first round.
The election is seen as an indicator of Egypt's more important presidential poll in late 2011. Mubarak, 82, has yet to announce whether he will stand and is widely believed to be grooming his son Gamal for succession.
"A number of questions that have been raised during the present elections are very likely to be raised in the next election," one Western diplomat in Cairo said on condition of anonymity.
The near absence of opposition parties in parliament means whoever stands for the NDP in the presidential election will face almost no challenge, a scenario which could raise questions over the president's legitimacy.
