"Our supply chain is very short and very transparent, while other supply chains go through many traders and wholesalers. We also have close relationships with both our growers and our customers, which has been an important factor in our growth."
Ms Boggiss said Heilala had always paid its growers above the market price.
She emphasised that the cost per serving was minimal, given that vanilla might make up only 1 per cent of a product.
"But large price fluctuations are damaging to the industry, and we don't want manufacturers to have an excuse to not use pure vanilla."
Heilala has scored a number of successes recently with high-profile deals to add vanilla to products such as Whittaker's Chocolate and Lewis Road Creamery milk and icecream.
Lewis Road Creamery chief executive Peter Cullinaire said vanilla was a highly concentrated essence.
"Very little volume is required to add flavour. In terms of impact on overall pricing, it's not too dramatic. We wouldn't look to pass that price on. My personal view is that companies like Heilala need to pass on pricing increases when they're impacted as significantly as they are."
