Seventeen coaches from sports as varied as mixed martial arts and para cycling have been nominated for the Coach of the Year Award, along with outgoing All Blacks coach Steve Hansen, but there's no sign of Robertson who led his side to its third Super Rugby title in a row.
And in spite of their historic achievements, there is also no sign of the Crusaders as a team on the comprehensive list of nominees.
- Robertson breaks his silence after losing out on All Blacks coaching job
- Robertson misses out on All Blacks top job
That string of title-winning seasons has only occurred once before in the 24-year history of Super Rugby - also by the Crusaders between 1998 and 2000 - while this is the first time a single coach has pulled off the feat.
Even more impressive is the fact that these three seasons are Robertson's first at Super Rugby level.
Foster, by comparison, was in charge of the Chiefs for eight seasons of Super Rugby between 2004 and 2011, and failed to win one single title.
However, even if Robertson were to be nominated, he'd have stiff competition for the overall award with Lisa Carrington's coach Gordon Walker bidding to win for a record four times in a row.
Other notable nominees in the category include Valerie Adams , who coaches her para shot-putter sister Lisa, Black Caps coach Gary Stead and Silver Ferns coach Noeline Taurua.
Another notable snub among the Halberg nominations is for 18-year-old skier Alice Robinson.
While Robinson is nominated under the Emerging Talent category, an argument can be made that she deserves to be amongst the nominees for Sportswoman of the Year after a history-making season.
Robinson became the first New Zealand skier to win a World Cup event since Claudia Riegler in 1997 after beating reigning world champion Mikaela Shiffrin in the giant slalom in Sölden, Austria in October.
The victory also meant she became the youngest woman from any nation to win the Sölden World Cup race.
That victory was preceded by a World Cup final silver medal behind Shiffrin in March and came alongside the world junior giant slalom title in February.
