Mantiyupwi Traditional Owners had long aspired to establish their own community store at Wurrumiyanga. Signing the Township Lease with the Executive Director of Township Leasing in 2007 and receiving an advance payment of rent helped to make this ambition possible.
In 2012 a commercial Sublease was granted to Mantiyupwi Pty Ltd, the commercial arm of the Traditional Owners, to allow for this development.
The new supermarket was built using funds drawn in part from the Township Lease advance payment with the balance raised through a loan over 10 years from a mainstream commercial bank. Notably this was also the first project in Wurrumiyanga to obtain a Development Permit from the Northern Territory Department of Lands and Planning since Wurrumiyanga was gazetted as part of the Northern Territory Planning Scheme.
The new supermarket was opened on 15 March 2013 during a simple ceremony by senior Traditional Owner Walter Kerinaiua Senior and named in honour of his grandfather.
The complex is comprised of a supermarket and four small retail outlets. Mantiyupwi Pty Ltd has a management agreement with Outback Stores to ensure a professional approach is taken to the operation of the supermarket and to provide training and employment for local Tiwi workers. Tenants of the other shop spaces include a takeaway food outlet and the Traditional Credit Union.
