Today, the Diamond Laundry Group, which employees over 110 staff, still includes the original business along with ApparelMaster, for work wear laundry and rental, and Central Linen Service for professional linen hire, cleaning and supply.

"When we started, no one could have anticipated how fast the international and domestic visitor market would grow and the positive impact it's had on the economy and jobs. It's enabled us to expand, diversify and employ more people."
Central Linen covers Hawke's Bay and the lower and central North Island including Wellington, Palmerston North and Taupō. All orders are delivered, and collected, directly to and from accommodation providers, large and small, from bed and breakfasts to five-star hotels, through its driver fleet from Whakatu with depots also in Taupō, Dannevirke and Wellington.
The busy team sort, wash, dry, press and fold approximately 150 tonnes of laundry a week.
"Our investment will create another eight full-time jobs. Unlike many other businesses where automation is replacing jobs, in the laundry industry we still require significant human resource to operate the production lines."
