Jones, however, may have seen himself ending up as a paralysed economic development minister in a Labour-Greens coalition which saw him having to constantly battle on behalf of any project with environmental repercussions.
Sure, there have always been questions about Jones' commitment to national politics. He has previously long pondered whether to stay in Parliament or cut his losses and return to the world of commerce, thus ending what has been a political career marked with a few highs, but definite lows.
The great tragedy for Labour is that the highs had been easily outnumbering the lows since the last election. Jones had visibly flowered and exuded confidence and authority following him putting himself forward for the Labour leadership last year after David Shearer stood down from the job. Labour cannot afford to lose MPs of such huge calibre and drawcard charisma. Neither can it afford to lose someone who talks political sense in a no-frills way.
His departure is a blow to those on the party's right who question the wisdom of Labour's perceptible drift to the left under David Cunliffe's leadership.
He might not have intended it, but his leaving is also a massive blow to Labour's morale at one of the worst possible times - just five months before election day when the party is endeavouring to motivate its membership to go door-knocking to get out the Labour vote.
The best that can be said is that Cunliffe will now not be overshadowed by anyone from his own side during the formal election campaign. That was always going to be a danger when Jones was around.
Regardless, the winners from Jones' going are John Key and the Labour left, unusual bedfellows to say the least.
