A group of 11 sponsors have signed agreements with the Pacific Games due to take place between July 7 and 30 in Apia.
The sponsors come from the private and public sectors, as well as state-owned organisations.
Digicel Samoa, Commercial Bank, Samoa Shipping Corporation and No 1 Currency are among the sponsors.
The portfolio also includes McDonald’s, Apia Insurance, Samoa Stationery and Books, the Samoa Ports Authority, the Electric Power Corporation, SkyEye and Accident Compensation Corporation.
Around WST 7 million (£2 million/$2.5 million/€2.3 million) in sponsorship has been raised to support the event.
With Samoa 2019 having had only an 18-month window to prepare after replacing Tonga as hosts, Tagaloa claimed the event was set to be a miracle.
"I would name this Pacific Games as the 'Mracle Games'," he said.
"We have seen the people rally behind us."
Tagaloa added: "It has shown a sign of belief and faith in the Organising Committee that is driving the Games.
"People believe we can succeed if we work together - it is comforting.
"[We are} grateful to our community and government for getting us to where we are now.
"Hospitality is within the DNA of our people.
"It’s our culture to have warm hearts and opening up our doors for people.
"As part of who we are in our daily life, hosting people comes naturally to us.
"For every athlete that will be representing Samoa, remember who we are founded on.
"The lions may grow weak and hungry but those who seek the Lord lack no good thing."
