The casualty list is consequently equally long. Claytgon Cosgrove suffers the ignominy of going from No 8 in the ranks to the obscurity of the pool of unranked MPs.
Also off the front bench are David Parker, who spat the dummy after being well-beaten in the election of the new leader, and David Cunliffe - perhaps the least surprising of Little's decisions.
Along with Phil Goff and David Shearer, the pair now sit in second row purgatory which sees them in reserve and possibly returning to the front bench at some point or - more likely in Goff's or Cunliffe's case - being their last stop before leaving Parliament .
Other noteworthy losers include Sue Moroney , who previously held the shadow Social Development portfolio, and gay marriage law change advocate Louisa Wall.
The reshuffle is very risky. Labour's new front bench has never looked quite so inexperienced.
It could be tough going in the House for some time as the new faces bed themselves in. Grant Robertson's appointment to the crucial role of finance spokesman perhaps sums that up.
Little's reshuffle also leaves everybody knowing where they stand - and whether they have a political future under his leadership.
One of King's jobs as deputy leader will be to rebuild caucus unity. She may well have her work cut out achieving that goal.
