His dynamic running and creativity out of dummy-half saw him rediscover his best form after his play suffered during his first two years at the Warriors (2016-17) as he battled weight and fitness issues.
His resurgence was rewarded when he reclaimed his Kiwis jersey for the June test against England in Denver before he finished the season among the nominees for the Dally M Hooker of the Year award.
The Warriors will be expecting more of the same from him next year as the club's first-choice hooker while looking to further blood young No 9 Nathaniel Roach who missed the entire season recovering from back surgery.
Luke's pending signing comes after the Warriors last week announced versatile forward Jazz Tevaga had re-signed for next season with an option for 2020, while the club has further depth in the position through back-up hookers Karl Lawton and Sam Cook.
Tevaga last week celebrated winning the Dally M Interchange Player of the Year after an impressive campaign that saw him come off the bench to play loose-forward while he also filled in at dummy-half in Luke's absence.
However, the extent of Luke's shoulder injury is still to be confirmed after he carried the problem throughout the season while also managing an Achilles strain.
Luke has a history of shoulder issues and missed the round 10 loss to the Sydney Roosters after suffering a dislocation in the previous week's win over Wests Tigers. The injury has ruled him out of next week's transtasman clash against the Kangaroos in Auckland and the Kiwis' end of year tour of the UK.
Warriors CEO Cameron George last week addressed the matter saying the club are willing to work with Luke to get the injury assessed, while his recovery could see him miss the start of next season.
"We all understand he's had a couple of injuries this year where he dislocated his shoulder on a few occasions," George told Radio Sport.
"At the end of the day that's something that the player needs to weigh up whether they go in and get it tidied up. The extent of that operation, I'm not a specialist in any way shape or form around MRI scans but his specialist will advise what that is in due course.
"If we need to work with Issac to get that done in order for him to play his best for the club next year, if he is here, we'll work with him for that."
Meanwhile, the Warriors on Monday confirmed former Kiwis World Cup winning captain Nathan Cayless has signed a two-year deal to coach the club's Intrust Super Premiership side.
The Warriors have also announced they will play a home game at Wellington's Westpac Stadium in each of the next two seasons. The date of next year's game will be confirmed when the 2019 premiership draw is released in November.
