The combination is the latest hybrid in sweet treats with other confectionery makers also jumping on the trend, launching products such as L&P chocolate and biscuits, Whittaker's K Bar and Jelly Tip range and Cadbury's kiwi flavour creations.
The manufacturing future of both Pineapple lumps and Jaffas has been in question after Cadbury owner Mondelez announced it was closing the Dunedin Cadbury factory next year and moving remaining production of its products to Australia.
Mondelez said it was hoping to find a local manufacturer to take on the production of some of its products.
A crowdfunding plan launched by Dunedin city councillor Jim O'Malley and a group of volunteers has received more than $5.5 million in pledges out of a total $20m to purchase the factory and keep manufacturing on the site.
Mondelez earlier said it had received a number of expressions of interest and would be working through them.
"Pineapple Lumps is the top selling lolly bag in New Zealand [according to Nielsen] and is a part of Kiwi pop culture," Rosman said.
"We wanted to pay tribute to one of the most-loved New Zealand products and have it join forces with another iconic lolly - the Jaffa."
Jaffa Lumps would be available from Monday for a limited time.
