The programme will support artists to develop their creative practice through a "unique" residency programme working with skilled craftsmen based at the foundry.
Gillies MetalTech Foundry programme co-ordinator Katherine Kovacs said the response to the inaugural pilot programme had been amazing, and the level of applications "high".
"We were initially looking for two artists to join us in August 2024, but due to the overwhelming response we received, we added another residency to take place in February 2025 for 16 weeks."
Oamaru-based artist Karen Aitken and Wellington-based artist Sian Quennell Torrington are the selected artists for 2024.
Aitken will start this month and Quennell Torrington in September.
The foundation, in collaboration with the Elam School of Fine Arts at the University of Auckland, will also host a doctoral candidate, Matthew Galloway, for a short residency late next month.
Dunedin-based artists Motoko Kikkawa and John Ward Knox will be artist residents for 2025, starting in February.
The next application period begins in March for August 2025 and February 2026 residencies.
