To that end, the party's strategists determined that yesterday's campaign launch would highlight a new(ish) policy to allow those in KiwiSaver to have their contributions to the scheme managed by the guardians of the New Zealand Superannuation Fund.
This "public option" would - the party says - make saving more attractive by cutting the high fees and other costs imposed by other KiwiSaver providers. The Greens say a 40 per cent cut in fees over a lifetime could increase retirement nest eggs by between $23,000 and $140,000 depending on contribution rates.
It may not have been the sexiest of topics with which to officially kick-off a campaign. When their savings policy is twinned with the Greens' advocacy of a capital gains tax, however, the party is seen to be making an almost textbook pitch for structural adjustments to the economy to enhance savings and boost investment in productive job-creating ventures.
Summarising all this in a sound-bite is not easy. Instead, the party has sought to condense its emphasis on the economy through its slogan "For a Richer New Zealand".
At the launch, Greens co-leader Russel Norman spoke of this meaning a "richer society" and a "richer environment". But there is no doubt the Greens want voters to also pick up on the meaning of "richer" in a financial sense.
The launch was also notable for the other co-leader, Metiria Turei, waving vigorously in National's direction. Turei indicated they wanted an "enhanced" memorandum of understanding with National post-election - one covering far more areas of mutual interest than the limited one negotiated during the just-concluded parliamentary term.
"We can get stuff done," she told the cheering party faithful. Whether that was in partnership with Labour or - as seems more likely - more loosely with National, did not matter particularly.
THEY SAID IT
* "We need a national standard for rivers - not children." - Actor Robyn Malcolm, the MC at yesterday's Green Party campaign launch.
* "When they're not spending the Government's money, they pass legislation to spend your money." - Finance Minister Bill English castigates Labour's promise to raise the minimum wage to $15 an hour as yet another cost imposed on business.
What's happening today: National to announce new policy to "pre-screen" parole hearings to cut the workload of the Parole Board. Hearings will only be held when there is a chance of the inmate getting parole.
