The visitors, who have set the goal of claiming the double this season (league and Chatham Cup national knockout bragging rights), will be without solid defender and co-captain Finlay Milne, who is nursing a hamstring injury.
"Fin's definitely out of the game tomorrow [today] but hopefully he'll be all right for the next round," says Robertson as the Rovers will host Wellington Olympic (Greeks) at Park Island in another league clash before reloading a weekend later on the home turf for Miramar Rangers in the third round of the Chatham Cup.
The Danny Wilson-captained Blues will today come off an 11-0 hammering of Lotto Federation campaigners Massey University in Napier on Monday, where several players experienced the warm fuzzies of scoring goals.
They will need that buzz now that striker Angus Kilkolly has gone to Lithuania for trials with professional club FK Panevezys.
The 20-year-old from Hastings, who scored seven goals in the Central League golden-boot race here as the Rovers' key forager, initially has designs on second-division offerings but is hopfeul first-division coaches will like what they see and shuffle him to the top.
Stephen Hoyle is still recuperating from an injury but, on the bright side, Josh Stevenson is finding lots of love from the nets.
So is playmaker Saul Halpin but midfielder Ryan Tinsley needs to come to the party more often.
Teenager Vinnie MacKirdy, who made his debut as a substitute away in the 4-0 win against Petone on April 23, shuffles back on to the bench as a midfielder while Ethan Ladd, a schoolboy defender, also joins him for the first time after making all appearances for the reserves.
"It's a good opportunity for younger lads to get some game time if they're doing well in the reserves or when we have injuries," says Robertson.
Needless to say, the return of versatile player Harry Morton is a godsend during his break from American university Hartwick College in New York state.
"His workrate's very good and he's got pace about him and technically he's sound, too," says Robertson of Morton who can defend or provide impetus on the wings.
Grape pruning, the 21-year-old chemistry/business administration major from Tikokino has helped his college side to their second conference title in a row.
In the NCAA tourney, they lost 1-0 to Dartmouth University in the last three seconds of double overtime.
"They are very athletic and big boys there," says Morton, who prefers the positional play back home "in the awesome weather here" before he returns late next month or early August.
"The Rovers are a top team in New Zealand," he says, looking forward to starting today and the next two top-tier clashes with a club he has played for since he was 11.
