NZ Post’s BigCommerce Transformation Drives 110% Customer Growth

Background

Established in 1855, New Zealand Post has issued side-profile stamps and special commemorative products for over a century. Its Collectables division offers rare stamps, coins and memorabilia to enthusiasts worldwide. Prior to 2021, the Collectables site ran on an aging Drupal system that lacked modern tools, SEO best practices and international scalability.

Challenges

The legacy platform was unsupported, prone to security gaps and unable to integrate with the existing on-premise ERP. Trading offline for 70% of transactions meant the team needed a cloud solution that would bridge their core order management and CRM, without vendor lock-in. They sought ownership, agility and a path to global growth.

Solution

After evaluating multiple vendors, NZ Post prototyped on BigCommerce, thanks to a recommendation by certified partner agency Goose. The overhaul included a rebuilt information architecture, seamless Dynamic 3i ERP integration and a mobile-first storefront for stamps and coins. The team also tapped BigCommerce’s SEO audit to apply backlinks, meta optimizations and content enhancements. To nurture audiences, they integrated Klaviyo for segmented email campaigns.

Results

Since launching, NZ Post has seen orders climb by 13% and revenue up 25%. Domestic transactions grew by 25%, while international customers nearly quadrupled with a 332% surge. Overall new customer acquisition leapt by 110%. The modern platform gave the team autonomy, improved site performance and made future expansion possible.

Looking Ahead

NZ Post plans to publish its catalog on social channels like Facebook and Pinterest, add Google Pay and Apple Pay for smoother checkouts, and explore marketplaces such as Amazon and Trade Me. Continuous SEO improvements and targeted Klaviyo flows will fuel sustained growth.
