In the new poll, 73% of Filipinos reported having "much trust" in him, versus 12% citing "little trust" and 15% who were undecided.
Trust and satisfaction in him fell to the lowest of his presidency in the third quarter of this year, a survey showed, although sentiment about his leadership remained positive overall.
"It is worth noting that surveys are snapshots of the public mood at a given time and the SWS survey was conducted between September 23 to 27, just two days after the National Day of Protest - the bold (Duterte) initiative allowing citizens to freely vent their grievances about the excesses and shortcomings of the government - and some sentiments may have spilled over", Abella said.
"(While) his government was focused on killing the poor and balkanizing our democratic institutions, his administration has miserably failed to deliver on his promises - peace in Mindanao, housing, solutions to traffic, end to "endo" (end of contract), employment, among others", the group said in a statement.
The Office of the Ombudsman is looking into the wealth of the Duterte family.
SWS clarified that the said survey was not commissioned but a part of the survey firm's initiative for public service.
In separate interviews, the senators agreed the survey results should serve as "a wake-up call" that Duterte can heed, or ignore at his own risk.
White House: Take Trump's priorities seriously, not his comments
A senior administration official said on Thursday that Trump was expected to announce soon he would decertify the landmark agreement.
Ifugao Representative Teddy Baguilat, a member of the House opposition, urged Duterte to use his political capital "to do what is right". More than 800 people have died in the ongoing battle.
"Hindi siya untouchable. Nalantad na ang kahungkagan ng kanyang pangakong pagbabago; ang brutalidad ng kanyang mga giyera kontra droga at kontra sa mga rebelde, na bumibiktima sa maralita sa kalunsuran at kanayunan; at ang hagupit ng kanyang mga economic policies, na pumapabor sa ilang mayaman at dayuhan habang hindi nagbibigay ng trabaho at serbisyo sa maralita", said Tinio.
"They are now seeing Duterte for who he really is: a lying, rude, amoral, corrupt and oppressive former mayor who is totally incompetent about governance at the national level", the former Navy captain said. The challenge is to maintain the trust of the majority of Filipinos.
Sen. Panfilo Lacson said the drop in the ratings of the President was "bound to happen sooner or later".
"Public opinion is quite malleable. easily shaped by twists and turns in current events", she said.
Duterte's allies in the Senate advised the President not to take the survey for granted.
Rep. Bernadette Herrera-Dy of the Bagong Henerasyon party-list agrees with Lacson, just that the recent weeks before the survey was conducted were 'generally not favorable for the President'.
