The former Titan has been a regular visitor — "Every time he calls, I tell him to send the request to let me go and see him" — but admits it will be emotional to be reunited with his sibling.
"I'm counting down the days," said Pulu. "It's been difficult being in Australia. Being back home, I can hopefully just pop around, and if he needs anything, I can help out."
Pulu also revealed his brother wants to use league as a vehicle in his ongoing rehabilitation.
"He has been playing footy inside prison and he wants to give it a go," said Pulu. "He has found the love for it. He doesn't tell anyone he's my brother, but hopefully he's proud of what I'm doing.
"He wants to come out and give it a go . . . he really wants to give it a good dig. He's lost a bit of weight, as they all do, stopped smoking, and he's looking better. He's coming out to better himself."
Pulu's return to Auckland, 12 years after he first left, caps an unlikely journey for the 27-year-old.
He was a promising school-age player — good enough to win a scholarship to Keebra Park High School as a 16-year-old.
Graduates from that famed Gold Coast nursery include Benji Marshall, Jordan Kahu, Greg Eastwood and Te Maire Martin, and Pulu looked on the same trajectory when picked up by the Tigers.
But it didn't work out, and the arrival of his first child also meant priorities changed.
"I became a father at a young age [19] and had to put my dreams on hold for a while to provide for my family," said Pulu.
Life was tough. Pulu worked a succession of different manual jobs from landscaping to traffic control as he focused on putting bread on the table for his family.
"I was a jack of all trades: A scaffolder, landscaper, a forklift driver, a security worker, a warehouse worker, a labourer, form worker. I worked in a bar, I unloaded containers, I did traffic control.
"But I never had a job where I was secure, it was just whatever I could get. I remember when my wife gave birth to my first child at 3am, I left the hospital at 7am and went to work straight away — just a grind. But I had to do whatever I had to do."
Pulu continued to play league, but hopes of a professional career were fading fast.
"It wasn't easy," said Pulu. "There were times when I was told I wasn't going to make it, I didn't have what it takes. But I was lucky to have a good support group and my wife was encouraging.
"Once, I came home from work and I said 'I'll just work, eh?' and she said 'no, keep going'. She saw I wasn't happy."
An off-season playing in France when he was 23 helped to spark his dream of making it in league.
"Looking back, France was a turning point for me. It made me realise how good it could be — all I did was play footy, which was the first time that had happened in my life. That lit the fire."
On his return to Australia, Pulu caught the eye of the Titans after a strong season with the Wyong Roos, and made his NRL debut aged 25 in March, 2016. Pulu's difficult path to the top has made him more hungry to succeed, as he's all to aware of the alternative.
"It has made me more appreciative of everything, to this day," said Pulu. "It was pretty hurtful at times but you have to keep going and hopefully let the tide change.
"I was lucky enough to get a break with the Titans. I wanted to give it my best shot and if it didn't turn out, at least I knew I gave it my all. Now I've got the chance to do more."
Warriors coach Stephen Kearney is a fan, and it seems likely Pulu, who has 45 NRL games behind him, will be part of the team to face the Rabbitohs in Perth in round one. At 1.92m and 111kg, he offers power and an intimidating edge, something sorely needed in the Warriors pack.
"He's brought a lot to the team, made a strong impression," said Kearney. "He's a guy that has worked hard to get where he is now and that shows . . . he's certainly putting his hand up."
