There will be no resting on laurels, even if the only significant losses from the 2015 group are outside back Nathaniel Apa, prop Nepo Laulala and goal-kicking ace Tom Taylor.
"We've had a good run [since 2008] and it's off the back of breaking every year down, but this group have their own goals to achieve."
That includes talented Chiefs loose forward Tom Sanders, wing Johnny McNicholl, who will join Welsh side Scarlets after the campaign, and young first five-eighths Jordie Barrett, fresh from a fine New Zealand under-20s campaign.
Interesting newcomers include Fijian-Crusaders No 10 Ben Volavola, former Auckland hooker Nathan Vella, 2015 Wanganui midfielder Poasa Waqanibau, former Fijian prop Lee Roy Atalifo, and former England under-20s flyer Nathan Earle.
New Zealand Rugby do not promote the draw as a separate Premiership-Championship competition, but that does not change the approach of the coaches, not when a clutch of Championship sides upset their higher Premiership rivals in 2015.
Robertson recalls, in particular, how North Harbour pushed them 17-10 last season and shocked them in 2014 in one of the great upsets in NPC history.
"There are hard games every week," he said. "Every team wants to knock Canterbury off. We know that and prepare accordingly. We've also got a Shield challenge [on September 28] if Waikato can truck through the first couple."
Robertson will watch a stack of rugby as he looks to fill the few remaining gaps in the Crusaders roster but also keep a close eye on trends and how his opposition are coping with the new laws.
"You've got to be quite smart and tactical How do you [legally] slow the ball down? Do you go through the middle or out wide?"
