The first was on non-communicable diseases and childhood obesity and the second dealt with disaster resilience.
Fiocco said that 15.6% of the adult population in Papua New Guinea had have Type 2 diabetes.
"Unfortunately this number is only increasing in PNG and throughout the Pacific and I have initiated discussions with the World Health Organisation representative here along with a few doctors to come up with strategies to reduce the burden of these diseases on our communities."
Fiocco said the PNG delegation - which included Foreign Affairs Minister Rimbink Pato and other private sector officials - also met with representatives from Nauru's private sector.
"We are told that the private sectors finds it challenging to do business there because the Nauru government often competes against the privately run businesses. For example, the government even operates a supermarket and state enterprises are often subsidised with costs like electricity.
"The private sector is interested in purchasing from suppliers in PNG. Most of their imports come from either Australia or Fiji," Fiocco said.
Fiocco appealed to PNG businesses interested in supplying products to Nauru to contact him at POMCCI.
