Tighthead prop Scott Vessey believes the Taniwha can build on their win against North Harbour and account for Tasman in their next ITM Cup match.
The former Canterbury player should know - he played a warm-up match for the province once and as many as four of his Christchurch club team will line up against Northland on Sunday.
He said their strength lies in their outside backs and loose forwards and defence will again be paramount for the Taniwha if they want to win the match.
The 26-year-old is acquitting himself well in his second season for the Taniwha. When he came off the bench against North Harbour on Sunday, the scrum improved immediately and his tackling stood out.
He said Tasman will be fatigued after three games in quick succession and that should be enough to tip the balance toward the visitors - if the Taniwha can stop making errors when in possession of the pill.
