The halfback and Eels captain batted away five queries about the one-year import from the Wests Tigers as his gaze remained firmly fixed on the club's fraying finals hopes.
"It's exciting for next year, but that's next year," he said.
"You can start talking about that (on) November 1, guys, you're not going to get much more out of me."
Moses and Luai last combined at five-eighth and halfback during NSW's successful 2024 Origin campaign, but hopes that the Parramatta No.7 would reflect on that experience at Tuesday's press conference were quickly dashed.
"He's not here yet, so I'm not too sure about club-land, what he (Luai) brings," he said.
"It was good in the Origin arena, but we'll have to worry about that next year."
Luai was unexpectedly shown the door from the Tigers a year early and will spend one season with the Eels before his much-publicised move to the PNG Chiefs in 2028.
Pundits have described Parramatta as "a halfway house for halves" after Jonah Pezet also made his home there for the current season en route from Melbourne to Brisbane.
But Moses was unfazed by the moniker, implying Luai would be an asset no matter how long he stayed.
"Every time you can get a player of this calibre and get him into the team - yeah, any day of the week," he said.
It comes during a turbulent season for the club's roster, with Eels players crowding the NRL casualty ward.
The 15th-placed Eels will seek to defy the stats tables in their match against the minor premiership hopefuls, who are expected to bounce back after losing in front of a home crowd to Brisbane last week.
Parramatta's 6-11 record has essentially turned all seven remaining fixtures into must-wins.
"The fight's been there pretty much the whole year," Moses said on Tuesday.
"We've been in and out of games, and (there have) probably been lapses there where it's 10 to 15 minutes ... just a bit of inexperience there, and it has been hurting us.
"We've got to be better for longer periods, and you know, the team that we're versing on the weekend does that."
The Eels' captain never underestimated the challenge posed by his opposite number at the Panthers Nathan Cleary, who silenced staunch criticism during a legacy-defining Origin decider performance.
"He (Cleary) copped a lot of abuse, which was unwarranted, and yeah, he's just put that to bed," Moses said.
"I was really happy for him."
