After breaking a 17-year semifinal drought, the Taniwha could go one step further and secure a home semifinal if results fall their way.
Northland first need to win their game, with a bonus point likely to help out if Hawke's Bay hold off Southland.
Taniwha fans should cheer for Southland in today's 5.35pm Ranfurly Shield match if the Taniwha are to have a shot at playing again at Toll Stadium.
However, Southland have the tough task of knocking over Hawke's Bay. For Southland, they must win to give them a chance at making the semifinals so they have plenty to play for - as if the Ranfurly Shield wasn't enough.
Bonus points may be enough to deny Northland the home semi, though.
