The win qualified CBRE New Zealand for entry into the worldwide awards, where it was pitted against regional winners from Europe, Britain, the Americas, Africa and the Middle East to decide the world's best property consultancy.
The event organisers said CBRE New Zealand's submission exceeded the criteria set, based on a company overview, marketing collateral, business services offered and the innovation of the company on a local level.
McGregor said winning the world award would give CBRE New Zealand worldwide exposure, support his office's international market campaigns and attract overseas investment to New Zealand.
"It has been proven that a direct result of winning the award is the generation of a significant increase in sales and business.
"Previous award winners have also reported higher brand awareness and heightened staff morale, so we are expecting a number of positive flow-on effects."
McGregor said the win demonstrated the value of global businesses having a strong local touch in their approach to services.
New Zealand had a unique property landscape, and the CBRE office looked to go beyond the adage of "think global, act local", he said.
