The cash machines at the Bureau of Customs – NAIA are on fire!
In a stunning show of force, the Bureau of Customs – NAIA crushed its assigned revenue collection target for April 2026, delivering another explosive victory for the country’s premier airport port under the fearless leadership of District Collector Atty. Yasmin “Yas” O. Mapa.
Inside the NAIA Customshouse during the May 4 flag-raising ceremony, the atmosphere was electric as top-performing offices and personnel were awarded Certificates of Commendation and Appreciation for their relentless contribution to the Port’s record-breaking revenue drive.
But behind the massive collections and intensified operations stands the iron-fisted leadership tandem now making waves inside Customs circles — Collector Yas Mapa and Special Deputy Collector Dr. Siegfred “Yeye” Manaois.

Known for their aggressive anti-corruption push and relentless enforcement operations, the Mapa-Manaois team has transformed BOC-NAIA into one of the government’s strongest revenue-generating ports, sending a clear warning to smugglers, corrupt brokers, and tax cheats:
“NAIA Customs is no longer business as usual.”
Sources inside the Port say the revenue surge was fueled by tighter monitoring, intensified assessment operations, stricter enforcement, and nonstop coordination among frontline units — all under Mapa’s no-nonsense command style and Manaois’ hard-driving operational supervision.
Observers say Collector Yas Mapa has emerged as one of the Bureau’s rising powerhouse leaders, earning respect for combining discipline, speed, and results at one of the country’s busiest and most sensitive ports.
Meanwhile, Special Deputy Collector “Yeye” Manaois continues to gain recognition for helping lead aggressive modernization and revenue collection initiatives that insiders say have significantly strengthened Port efficiency and accountability.
The Port’s latest achievement also reinforces the marching orders of Customs Commissioner Ariel F. Nepomuceno, whose battle cry of Integrity, Accountability, and Customs Modernization continues to fuel intensified collection and anti-smuggling operations nationwide.
With collections soaring and enforcement tightening, one thing is becoming crystal clear inside NAIA:
Under Yas Mapa and “Yeye” Manaois, the Bureau of Customs – NAIA is no longer just collecting revenue — it is dominating the game.
