The Raiders are on a mission to disrupt the festivities. They have missed out on the finals but can show their Aussie comrades the template to blunt the Warriors' hopes of a first NRL title and maybe soothe a little of the frustration coach Ricky Stuart has carried through another difficult campaign.
If they find the template of completed sets and few errors, their big pack will gnaw at the Warriors' resistance and open up chances for dangerous backs.
Where few pundits were concentrating on the Warriors when the season started, that focus has shifted as the competition has moved through the heart of winter. It will get even more intense after this weekend if the Warriors earn a home ground draw in the playoffs.
Ticket prices will cost more than tonight but Mt Smart will sell out again.
When the Warriors sting, the backline riches of captain Roger Tuivasa-Sheck, David Fusitu'a and Shaun Johnson often get a large chunk of the attention. That's understandable. They are dangerously talented athletes to match any in the NRL and that flair hogs the headlines.
However, the balance in the improved Warriors' pack is the foundation for their push to the playoffs.
They have worked hard to pair their defence to their ball-playing instincts. Experienced hooker Issac Luke has brought a consistent threat with his variety, Adam Blair adds to the reliable drive alongside Mannering while Tohu Harris has brought the dynamic punch.
In the trenches, James Gavet and Agnatius Paasi have motors to match their intent and when they need a spell there is strong backup from the pine.
As the Warriors have profited from their work, they have gathered crucial confidence about their ability to trouble any side in the NRL. To sustain that belief and to salute Mannering's remarkable career, the Warriors owe it to themselves to do the business tonight.
