The video has been viewed more than 87,000 times on Facebook, and led to Ms Foote being interviewed on TV1's evening magazine show, Seven Sharp.
The auction site has also taken more than 6000 hits, still has a week to run, "and is almost up to a grand already".
"Part of the reason I wanted to do the Adele Welcome was to show that New Zealanders can think outside the square and that we can be a bit different," Ms Foote said.
"Mine was an 'artist welcome' but that's just one example. We are such a creative country there's so many ways we show that."
Adele to-a-T as the large portrait is, and warm as the welcome message is, it is the stardust effect revealed in the video that is its real magic.
"It's not a masterpiece. The painting itself was created for the video rather than the other way round, but it is striking," Ms Foote said.
"I think Adele's still in New Zealand on holiday. I'd love her to sign it, then we'd really make some serious money for KidsCan."
It was easy choosing a charity that might benefit from the artwork.
"Giving kids shoes and meals, fighting child poverty . . . what could be more worthwhile than that?"
Meanwhile, the charity is very excited about the artwork and Ms Foote's gesture.
"KidsCan is grateful for Jessie Rose's time, energy and talent with a stunning piece of art which will not only raise much-needed funds for New Zealand children living in hardship, but show appreciation for another talented artist, Adele!" KidsCan CEO and founder Julie Chapman told the Northern Advocate.
Ms Foote said she has been portrayed as an Adele super-fan, but that's not the case.
"I'm not a super-fan but I do like her. I think she's a genius songwriter but mostly I think she's a good role model for women."
Ms Foote said she was worried people might think the home-made style video has already been over-exposed, but the more exposure the better for KidsCan, she said.
"I'm all for getting it out there. Imagine if I could have it on display in an empty shop window in town, with the video showing," she said of the possibility of reaching more potential bidders.
