Davidson held the reins of a pink-maned unicorn in one hand while clutching a wad of cash in other.
In front of her, a smiling Chloe Swarbrick third on the party list throws cash in the air.
Luke Wijohn, a candidate for Mt Albert, shared the photo widely on Twitter.
In one caption he said: "The honest and serious Green Party vision for Aotearoa (and we're not joking)."
"I didn't know I needed @MaramaDavidson on a unicorn mocking New Zealand First but oh my god I'm glad we have it," tweeted the director of Auckland Pride, Max Tweedie.
"I'd love to have been the fly on the wall to that planning convo," one Twitter user responded.
'Where can we source a full sized unicorn from?'"
"My favourite part is how they 1-uped the NZF pic by having Marama Davidson RIDING the unicorn," said another.
"A+ work there"
Among the supporters included Kiwi actress Lucy Lawless, who retweeted Tweedie's message.
Winston Peters himself repsonded to the take on Twitter: "Told you so...but where's James...?", referring to absent co-leader James Shaw.
