Deloitte New Zealand to support SBS Bank’s core banking transformation with Engine by Starling
Deloitte will bring the strength of its Converge BankingSuite to the modernisation
Auckland, 09 March 2026: Deloitte New Zealand has been appointed as implementation partner for SBS Bank’s core banking transformation. This follows the bank’s newly announced partnership with Engine by Starling, Starling Group’s global banking Software‑as‑a‑Service business.
SBS Bank is one of New Zealand’s longest-standing member-owned financial institutions. A partnership between SBS Bank, Deloitte New Zealand, and Engine by Starling, marks the start of a transformation that, over time, will support a more modern and secure banking experience.
By upgrading its core banking system to Engine’s secure, cloud-native banking platform, SBS Bank will enable its members to benefit from world-class digital onboarding, accounts, and smart money management features through a new intuitive mobile app, while also streamlining internal operations and reducing complexity for teams. As implementation partner, Deloitte will bring proven delivery expertise across both banking transformation and large-scale technology modernisation, supporting SBS Bank through every stage of the multi-year programme to ensure it is delivered on time and at the highest standard.
“We’re proud to support SBS Bank on this significant modernisation journey. This programme will enable SBS Bank to deliver exceptional digital experiences to its members while building the operational resilience and agility required for the future of banking,” says Partner at Deloitte New Zealand, Grant Frear.
As part of the transformation, Deloitte will also bring the strength of Converge by Deloitte, a modern and flexible composable suite of industry‑ready capabilities designed to help banks, mutuals and building societies introduce new digital services faster, reduce development effort, and scale innovation more effectively.
“Deloitte’s global transformation capability, combined with local expertise, means we are uniquely positioned to help bring this vision to life. We look forward to working alongside SBS Bank and Engine by Starling to deliver a modern and resilient banking experience,” continues Frear.
Deloitte is bringing the best of its global capability to SBS Bank, drawing on delivery experience from Australia and the UK, alongside the deep local banking and transformation expertise of the New Zealand team.
SBS Bank’s Group Chief Executive, Mark McLean, said the transformation represents a major step in the bank’s evolution.
“We’re pleased to be working with Deloitte, building on our existing relationship and their proven expertise, as we focus on becoming a more resilient and future-ready bank. Together with Engine by Starling, we have a strong partnership in place to deliver better experiences for our members, communities, and more modern ways of working for our teams,” says McLean.
