About seven people were already employed at the new Taupo branch, with Tremain looking to move the sales force from four to about 10.
"We've always been happy to stay in Hawke's Bay but now we have got the Colliers International and Sotheby's International brands working well for us, there's an opportunity to expand into other regions under those brands and then launch a Tremains to the main market."
Subject to how the Taupo operation performs, Tremains would be looking to open another branch further north in the future.
Founded by former All Black and local rugby legend Kel Tremain in 1970, the company operates in Napier, Taradale, Hastings and Havelock North, with another branch set to open soon in Waipukurau.
"We will be setting up Tremains in Waipukurau, and maybe looking further south as well."
FOOTNOTE. An earlier version of this story mentioned there were no locally owned and operated Real Estate businesses in Taupo. Gemma Miles, the principal/owner of B&W Real Estate has got in touch to let us know that her business is locally owned and operated in Taupo.
