Honouring his family is central to his efforts in Toa Samoa blue.
"It's pretty massive, all the players can say that as well - no matter what country you play for, once you go back to your mother country, it's a whole different ball game. It means so much more, trying to give back to family," Maumalo said.
"That's pretty much why I'm here in the first place, because of them."
This idea is well reflected in the Toa Samoa camp.
The team tries to speak primarily in Samoan - barring the instructions of Australian coach Matt Parish - and conducted their pre-Cup camp in steamy Apia.
For the Australian and Kiwi-born players in the squad, such as Maumalo, it has been a great way to get back to their roots and bond with new teammates.
They were all gunning for the same goal - to knock off pool opponents Scotland, Mate Ma'a Tonga and New Zealand. The quarter-finals - and beyond - then await.
Samoa have never progressed past the quarters of a Rugby League World Cup and have set down a final-four berth as their minimum target.
"The boys here come together as usos [brothers in Samoan] and we try to bond as brothers. It's always good to come to these sorts of camps," Maumalo said.
"This is my first World Cup, that's a massive goal I've achieved."
