One New Zealand expands Rimini Street Oracle support

One New Zealand has expanded its partnership with Rimini Street, with the agreement focused on support for the telecoms group's Oracle systems.

The arrangement is intended to keep key Oracle platforms stable while freeing budget and staff for AI-related work across the business.

One New Zealand, which serves 2 million customers with mobile, broadband and satellite services, uses Rimini Street to support a complex Oracle estate that includes Siebel CRM, Oracle Database and other Oracle applications. The support has helped it avoid upgrades and redirect spending to newer initiatives.

Chief Information Officer Adrian Albuquerque said the relationship with Rimini Street stemmed from his experience with the supplier at a previous employer and has since become part of One New Zealand's broader technology planning.

"I've had great success with Rimini Street from my previous organisation, and so when I sought out a partner to support our Oracle systems, they were the first call I made," said Adrian Albuquerque, Chief Information Officer, One NZ.

He said that support for Oracle systems is tied closely to the company's AI plans.

"As we plan and execute our AI-driven transformation, keeping our systems secure, stable and operational is essential. Rimini Street makes that possible and gives us confidence and bandwidth to focus on what's next," Albuquerque said.

Browser issue

A key moment in the partnership came when Microsoft ended support for Internet Explorer 11, which One New Zealand relied on for its Siebel CRM environment. Rimini Street addressed the issue through its browser interoperability product, allowing the CRM platform to run on alternative browsers without upgrading the core system.

That avoided what One New Zealand described as a disruptive and expensive technology change at a time when browser support had become urgent.

"Instead of taking on a costly, disruptive upgrade just to address a time-sensitive Microsoft Internet Explorer 11 interoperability issue, Rimini Connect for Browsers made it possible for our CRM to run on any alternative browser, whether it's Microsoft Edge or Google Chrome. Rimini Street gives us the ability to choose our own roadmap and to keep all systems running smoothly while we make decisions on what's best for our business," Albuquerque said.

Billing systems

The companies also worked on the transition of One New Zealand's core billing engine to a new hardware platform. According to the telecoms group, Rimini Street helped identify issues across the application, database and technology layers before the system was stabilised in production.

That work supported the rollout of the billing environment without disruption and allowed internal teams to spend more time on new products and skills development.

"At One NZ, we are passionate about reimagining what's possible, for our teams and for the business," Albuquerque said. "With Rimini Street providing expert support for our Oracle systems, they've freed up my team to focus on new skills, new technologies and new opportunities, like opening a satellite service with SpaceX, for example. This would not have been possible if my team were stuck resolving issues."

Albuquerque also described the supplier as a long-term technology partner for customer management and billing platforms.

"Rimini Street is our go-to CRM and Billing expert, and the years of working together to deliver successful outcomes is our why," Albuquerque said. "As a CIO, I have to think years ahead, and that includes whom we select to guide our vision. Rimini Street isn't just an expert support provider; they're our co-innovation partner."

Rimini Street said its work with One New Zealand spans support and interoperability services for Oracle systems that remain central to daily operations. It positions this model as an alternative to vendor-led upgrades and migrations, particularly for organisations seeking to maintain older but still important software estates.

One New Zealand's comments highlight a common issue for large companies with legacy technology: balancing the need to keep core systems running with pressure to invest in AI and other newer programmes. In this case, the telecoms provider said external support has helped it manage both demands at once.

"We're proud to serve One NZ to strengthen their ability to serve its millions of customers across New Zealand," said Nancy Lyskawa, Executive Vice President and Chief Client Officer, Rimini Street. "Whether it's keeping Oracle systems running strong, protecting business uptime, solving complex technical challenges, or providing vendor-agnostic guidance, at Rimini Street, we stand behind our promise that 'We'll Get You There'.
