Moroney has given the Government considerable gyp over the extension of paid parental leave, while Wall steadfastly shepherded her gay marriage bill through Parliament.
The meritocratic principle seems to have gone AWOL, however, in the cases of the two Dunedin MPs. David Clark, widely seen as a possible future leader and thus a potential threat to Cunliffe, drops from 12th to 20th. Clare Curran has also paid the price of being on the losing side and has been stripped of broadcasting responsibilities and goes from 18th to unranked.
However, for every Curran, there is a Chris Hipkins. He ripped into Cunliffe last year following the party's tumultuous annual conference. His punishment is to keep the prestigious shadow education portfolio and jump two spots to eighth and a seat on Labour's eight-strong front-bench.
Meanwhile, Annette King, likewise a Robertson backer, not only keeps her front-bench status, but climbs to fourth - a remarkable achievement for someone who entered Parliament nearly 30 years ago.
The pair are on the front-bench for a reason, however. Cunliffe wants his best "attack dogs" there to harry and hammer National ministers.
Meritocracy has been applied where it helps Cunliffe meet his priorities, the prime one being to strengthen Labour's firepower going into election year. In that regard, yesterday's reshuffle passes the test with flying colours.
