From July 1 2026, Tower will take over as the underwriter for Westpac’s house, contents, car and vehicle insurance products. The deal follows what Westpac describes as a “thorough review” of its insurance distribution model.
Sarah Hearn, Westpac NZ’s managing director of product, sustainability and marketing, said the bank was keen to align with a domestic insurer focused on innovation and service. “We’re pleased to be partnering with an innovative locally owned and operated general insurer with a strong customer focus,” Hearn said.
She emphasised that for many customers, their homes and belongings are their most valuable assets, and that confidence in claims support remains critical. “That’s a responsibility we take incredibly seriously,” she added.
Tower, which has been providing cover in New Zealand for more than 150 years, has twice been named Insurer of the Year in the home and contents category. Its digital capabilities and competitive pricing were cited by Westpac as key factors behind the partnership.
The company claims customers will gain access to new functionality through Westpac’s online banking platform, including personalised insights derived from Tower’s risk data and analytics.
Tower has also built a reputation as a leader in using property-specific modelling to evaluate exposure to climate-related events. Westpac said it intends to collaborate with the insurer on national adaptation frameworks and improving the transparency of natural hazard information.
For insurance professionals, the transition is notable: IAG, which currently underwrites Westpac’s general insurance offerings, will step back after years in the role. While the bank has confirmed that existing policies remain in force and no action is required by customers, the shift marks one of the most significant bancassurance moves in recent memory.
The change highlights the increasing importance of digital integration, data-driven risk assessment and climate adaptation in distribution partnerships. As competition intensifies, insurers’ ability to embed analytics into customer platforms may prove decisive in securing similar deals.
Hearn thanked IAG for its longstanding relationship with the bank, but said the future lies in pairing Westpac’s customer reach with Tower’s technology-led underwriting.
“We look forward to sharing more about the new partnership from July next year,” she said.
