Churches, secular organisations including youth groups and schools extended a helping hand to Venezuela migrants, who left Trinidad to register at the Tobago centre.
They provided blankets, water, breakfast, lunch and snacks, as the migrants braved the hot sun, waiting in line days before registration was due to end on June 14.
From Sunday afternoon, hundreds of migrants began pouring into Tobago by plane and ferry, fleeing long lines at the two other centres in Trinidad.
Some registered and returned to Trinidad, but others remained as their numbers had not called as yet or they needed additional information to complete their registration.
After seeing the migrants' plight, the Seventh Day Adventist Church was the first organisation to offer assistance.
The church offered their Scarborough Harmon school compound as a base for showering and sleeping at nights.
During the day the church gave the Venezuelans three meals per day.
Diamond Andrews, of the Adventist Service and Industries Tobago Chapter, told Guardian Media the church helps those in need.
"We have done several outreach humanitarian programmes over the years and will continue doing so after this has ended," he said.
Pastor Terrance Baynes of the New Heritage Christian Fellowship shared similar sentiments.
Baynes said his church has helped the migrants and will continue doing so until the situation has ended.
"In this country, we have no reference point for this as we have never seen this kind of crisis before. What we are doing is out of love for mankind", he said.
His church, with assistance from Lisa Hospedales- a Tobagonian married to a Venezuelan - has housed and fed more than 16 migrants, at the church's Stumpy Bypass Road, Canaan compound for many nights.
In addition to the church, business organisations began to help.
Diane Hadad, Chairman of the Tobago Chapter of the Trinidad and Tobago Chamber of Industry and Commerce said the organisation had been helping quietly.
"Our position is that they are human beings in need and that as a country filled with human beings ... we should be there for each other", said Hadad.
"We have done our own little thing in the night, but we prefer not to speak about it...if you are doing something from the goodness of your heart, you are not supposed to put it out there on the radar," she added.
