The business development manager for NOW qualifies for the Cook Islands side through his father Tuk. The first test will be played in Rarotonga on June 30 and the second in Hong Kong on July 7.
"If the series is drawn the team with the best differential will qualify for the next stage in the qualification process. I played against Hong Kong when I was in the Chiefs Development team in 2015 ... I never thought I would be back," Uriarau said.
"The Cook Islands selectors saw me in action at the Sevens Heaven tournaments in Rarotonga last year and in 2016. Both Zac [Guildford] and I played in them ... he's a star over there."
Uriarau left the Bay at the start of the 2015 with the aim of cracking the Bay of Plenty Steamers ITM Cup squad. However after a couple of pre-season games for the Steamers he required double hip surgery.
"My body was pretty knocked around after a big 2014 year. But I've had no issues with the hip since then and I'm just enjoying playing my club footy again."
In 2014 he scored eight tries for Poverty Bay in their Heartland Championship campaign after scoring 16, including back-to-back hat-tricks for Napier Pirate Rugby and Sports. Uriarau is enjoying being back with the Taradale club who he played for from the age of four up to 12th grade level and gained Napier A, B, C and D rep team selection from.
"It's a shame I'm going to miss the next three games but I'll be back to help the boys out as much as possible when I return. Yes Tech were missing a few of their players at the weekend but that result was a step in the right direction for us."
A former Hawke's Bay age group rep who had two years in the Napier Boys' High School 1st XV, Uriarau, has no plans to chase any form of rep selection upon his return from Hong Kong.
"It's important I just put my head down and focus on the overseas stuff for now," he added.
