In his view, that epitomises where Hawke's Bay stands as the club puts players through its system only to develop them but lose them.
Finishing as high up the ladder as possible is another incentive.
"We'll go with the mindset of trying to win the game and see how far we can get," he said, emphasising the ongoing challenge players face in putting themselves in the shop window of the summer national league to secure contracts.
"We want to support and push players to the next level by putting in solid performances and having good wins to help raise their profiles over winter but it'll also be helping the [Rovers] club as well."
Robertson was mindful Wairarapa were coming off a rampant victory over Wellington United in the previous round.
"I don't look too much into what they're doing. I think their strength is they've got very good individual players so they pretty much have national league players to choose from," he says as Wairarapa have come out 2-0 winners in their two clashes this season.
