Prime Minister Jacinda Ardern has shared the adorable attempt of her young fan on Facebook, a voting paper complete with drawings of the candidates.
"I love this," Ardern wrote. "Got a letter from a 6-year-old who was so upset to learn they couldn't vote, that they created their own ballot paper. Bless!"
The PM added: "If you haven't voted yet make sure you do, because there's a 6-year-old out there who would love the same privilege."
The leaders have fired verbal barbs at each other, with Ardern calling Collins "morally wrong" on climate change, "desperate" with her ongoing claims about the Greens' wealth tax, and "simplistic" in her comments about personal responsibility and obesity.
For her part, Collins told media that Ardern had lied over the testing of border-facing workers and she hoped the Labour leader would sue her because she was "happy to prove it".
And Collins continued to raise the scenario of Labour folding to the Greens and adopting their wealth tax in post-election negotiations.
Ardern has repeatedly dismissed this as "fiction" and "misinformation", and she did so again yesterday.
"I have said the same thing on this policy no less than probably 50 times. I have ruled it out," Arden said.
"What you're seeing from the National Party, frankly, is desperate."
Ardern also responded to Collins' suggestion that the Labour leader was subservient to the Greens when it came to coalition talks.
"I'm not someone who takes chocolate biscuits to the bargaining table to show subservience," Collins said.
Ardern: "I brought ginger loaf [in 2017 talks]. And that's just good baking."
