"They said 'oh yeah, okay, thank you for your input' kind of thing and nothing much happened."
Until this week after Tasti started a campaign to find him. They had turned Hemi's ideas into Tu Meke products, and started a fund to thank him.
Finding Hemi - who hails from Moerewa - had proved difficult after he switched phone companies and phone numbers.
Northland newspaper The Northern Advocate publicised the search on its Facebook page on Thursday and, within hours, had three Hemis claiming "it was me".
"Two were a little unsure, the real Hemi was easy to identify," Advocate editor Craig Cooper said.
Hemi was impressed to find three of his suggestions - Coconut Rough, Choc Orange and Hokey Pokey - had been created and put to the public vote.
The most popular will become a regular Tasti treat.
Hemi hasn't tasted any of his flavours yet and still has a hankering to see his kiwifruit and pineapple lump suggestions become reality. He's also grateful for the money coming his way - at least $200 and was considering donating it to charity.
Michael Tohill, Tasti brand manager, said Hemi was very humble.
"We're looking forward to thanking him for his great idea."
Fans have until the end of August to vote for their favourite Tu Meke bar flavour.
For each vote, Tasti will make a donation to the "Chur Hemi Fund".
"We'll review the total funds raised at the end of the voting period then Tasti will add a further contribution. The grand total will then go to Hemi."
