Purple Tomatoes: NZ Regulatory Review

The landscape of tomato innovation continues to evolve, with genetically modified (GM) purple tomatoes emerging as a notable development due to their enhanced anthocyanin content, known for antioxidant properties. While these distinctively colored tomatoes have already made their way to American consumers, their potential introduction to New Zealand is now under review.

Prior U.S. Commercialization: The GM purple tomato, developed by Norfolk Plant Sciences (a spinout from the John Innes Centre in the UK), gained regulatory approvals in the United States from agencies like the USDA and FDA. Seeds for these high-anthocyanin tomatoes became available to home gardeners in the U.S. in early 2024, with fresh produce sales planned for grocery stores later that year. This marked a significant milestone, making a bioengineered crop with direct consumer benefits widely accessible in the U.S. market.

New Zealand’s Regulatory Process: In New Zealand, Food Standards Australia New Zealand (FSANZ) is currently calling for public comment on an application to permit the sale and use of food derived from these GM purple tomato lines. The tomatoes incorporate genes from the snapdragon plant (Del and Ros1-N), which enable them to produce anthocyanins throughout both the skin and flesh. FSANZ’s safety assessment has concluded no public health or safety concerns, deeming them as safe as conventional tomato varieties. If approved for food use, they would be subject to GM labeling requirements under the Australia New Zealand Food Standards Code. It is important to note that while food use is under consideration, commercial cultivation in New Zealand would require separate approval from the Environmental Protection Authority, and the importation of viable seeds is subject to specific biosecurity regulations. The public consultation period for food use is open until September 10, 2025.

For the processing tomato industry, these developments highlight ongoing innovation in raw material characteristics, offering potential for products with enhanced nutritional profiles and distinct visual appeal. The phased regulatory approvals underscore the varying approaches to GM crops in different global markets.
