Domestically with one game to go its quite simple.
ND 29Otago 24
Canterbury 20
CD 18
Auckland 14
Wellington 12
Northern guranteed first and from then on its simple: It rains in Invercargill Otago get two points move to 26 meaning we don't have to do anything and get a home semi even if Canterbury beat ND (unlikely) and CD beat Auckland fair chance.
