ANC members of council, who now sit on the opposition benches, left the auditorium en masse in apparent protest, moments before Trollip was presented with the gold mayoral chain.
The proceedings were handled by the newly elected council speaker, Jonathan lawack, who also performed the duty of swearing in UDM's mayoral candidate, Mongameli Bobani, as the deputy mayor with Werner Senekal as chief whip.
In his inaugural address as mayor Trollip immediately paid tribute to Olympic gold medallist Wayde van Niekerk and silver medallist Luvo Manyonga for their inspirational performances in the Rio Olympics.
He also thanked the likes of Govan Mbeki, Raymond Mhlaba, Nceba Faku, the first mayor of Port Elizabeth as well as former and current DA councillors Bobby Stevenson and Angelo Dashwood, for the role they played in paving the way for a post-apartheid society.
"This is testimony to the hard fought determination by the coalition partners to arrest the downward trajectory we have been in and to convince voters that change was needed, I am honoured to be part of it" he said.
Trollip also added that it was a big responsibility to deliver good governance in a city named after former president, Nelson Mandela.
"It is humbling that in the city named after our iconic President, Nelson Mandela, that it is now our responsibility to cooperate with other opposition parties in the spirit of reconciliation and redress to deliver good governance to the people of this city. I witnessed the excitement and will of the people regarding reconciliation and cooperation in front of City Hall on Saturday the 6th August 2016, where over 5000 residents joined hands in an overwhelming endorsement of change. It was a sight that would have made our late National hero so proud and one that will be indelibly imprinted in my mind." he added.
In a wide-ranging speech, Trollip said he identified three key priorities as mayor which include stopping corruption in Nelson Mandela Bay, creating jobs and delivering better services.
"Corruption is the enemy of freedom and fairness and the thief of opportunity. There will be no more erosion of municipal resources due to corruption procurement practices. There will be no more wasting of our resources on the glitz and glamour of irrelevant pubic events, flashy cars and wasteful expenditure on cadre deployment" he said.
Focussing on unemployment and job creation, Trollip said youth unemployment rate was at 47% meaning one in two young people are without work.
Trollip said his office would create a jobs desk at the mayor's office which has already been established in the city of Cape Town.
"In order to closely monitor and evaluate our commitment to job creation I will be establishing a jobs desk in the Mayor's office to ensure that jobs tops my daily agenda. This desk will facilitate queries and process applications for municipal bursaries as well as open a channel to incentivize businesses to employ first time job seekers; every possible avenue in this regard will be explored including the possibility of introducing a youth wage subsidy" he said.
Trollip also said the metro would focus on eradicating the bucket system by the end of 2017 to provide dignified sanitation for communities.
"It is time for this metro's 30 000 bucket toilets to go. We will also embark on designing and budgeting for a sustainable and dignified sanitation system in the burgeoning informal settlements in our city. What we cannot have are communities that are decades old still using the bucket system. Let alone having communities in new housing developments having to use buckets." he said.
Trollip said he would prioritise the exploitation of the metro's potential as a tourism destination as part of the DA's economic growth-plan for the city.
"Under this new government in conjunction with the Eastern Cape provincial Government and neighbouring municipalities, especially the DA led Kouga government as well as the DA led Western Cape provincial and municipal governments, Nelson Mandela Bay can become the next best tourism destination in South Africa and create thousands of new jobs" Trollip said.
Newly elected deputy mayor Mongameli Bobani of the UDM, told the media after Trollip's speech that people of the Metro were waiting for a big change.
Bobani also had these words for ANC councillors who walked out of the auditorium before Trollip's speech.
"We are expecting an opposition party that is robust however, that is not going to tear the council apart. We are expecting them to play an oversight role. So we are ready to work with them" he said.
Meanwhile, proceedings were delayed by ANC members who arrived thirty minutes late stating they weren't allowed inside the venue.
ANC's Andile Lungisa also said former NMB mayor, Danny Jordaan, was also locked outside of the Feather Market Centre.
Lungisa also stood up a number of times to raise a point of objection, also objecting the notion to elect Trollip as mayor.
"The substance is not there in his speech, it is even denouncing those who fought for freedom in this country. You cannot embrace the freedom which was delivered by ancestors which today cast in aspersion against those ancestors" he said to Algoa FM News.
Lungisa also touched on the alleged letter sent by the ANC's lawyers in Cape Town urging the acting municipal manager, Johann Mettler, to postpone this morning's council meeting.
Mettler, who confirmed the letter this morning to Algoa FM News, said the ruling party was unhappy with the allocation of PR seats.
Lungisa said there were a number of different of legal procedures of the system which have not been clarified.
"You must remember that we have raised the issue of the dispute, how the council is constituted. You must remember that there are a number of legal floors which are part of the process which have not been clarified and addressed" he said.
He also added, that the responsibility of the ANC is to focus on communities.
"We have to make sure that all the wards which we have won as the ANC that service delivery takes place. Our people are assisted and they are helped†Lungisa added.
Council speaker, Lawack, said the ANC's deliberate attempt to derail the election of a new mayor, deputy and speaker will not be tolerated.
He said councillors were aware that the meeting would start at 10am.
"I will not during my term here allow members of council to forget what they are really here for. It not to be technical, it's not to raise nonsense issues, it is to deliberate on matters that will enhance service delivery. That will be the focus and if anyone veers off, I will be the one to state that unequivocally that they are not serving the people" he said.
Trollip said the rest of the DA's council would be elected next week Thursday at a special council meeting.
He also added that he would reveal his plans for his first 100 days in office at the special meeting.
