In its half-year results, the franchising powerhouse was up 14.6% year-on-year to £12.1m (approx NZD 33.109m).
The firm showed strong growth in earning before interest, taxation, deductions and amortization (EBITDA) to £1.6m NZD 4.37m), an increase of 22.3% on the equivalent period last year.
Finance director Alan Roberts said the results "predominantly show the strength of the UK operation" but added that the overseas expansion continued to show promise.
He said that its first international master licensee in New Zealand was going well and providing a "reasonable income stream", while new Icelandic partner, £70m (NZD191.5m) (€100m) turnover KVOS, was now trading.
Roberts added that the firm had begun shipping to France via its Manchester hub, with long-term plans to sell a master license in France.
