RACHEL COLLEVILLE

Operations Manager

Licensee Salesperson

Joining Team Tatana, whose mantra is “Real Estate without Borders”, Rachel is entirely akin to the team’s ethos and hard-working ethics.

Still, for Rachel, it’s not only real estate without borders; it’s communication and connection without borders. As an easy-natured French native, who has travelled many continents as a French teacher with a master’s degree in linguistics, Rachel’s naturalness for listening and reading people is her virtuoso.


Calling New Zealand home for over 10 years, Rachel has had applaudable success in management within the country’s travel industry. Yet after experiencing the adrenaline-charged process of purchasing her own Auckland home, the call to the real estate was too strong to ignore. With her tact for organisation and detailed workstyle, alongside the added value as a real estate licensee, she takes full charge of the delicate components of business as the team’s operations manager and an active property seller.


Never shy when tackling tough matters, and ready to lighten the moment with good humour, it’s a genuineness to make others happy that precedes her honest determination.
Together with the highly capable and knowledgeable expertise of Team Tatana at Ray White Ponsonby, Rachel couldn’t be better positioned or prepared to meet high expectations and outdo them.
