Otago sit in second, 18 points behind their southern neighbours, and have a realistic shot to win the four-day competition for the first time in a quarter of a century.
Canterbury, meanwhile, have the opportunity to create some more breathing space when they host third-placed Central Districts in Rangiora, while Ish Sodhi returns for Northern Districts as the cellar-dwellers welcome Wellington to Whangarei.
