Real estate agents are being warned to watch for collusion by property investors after revelations in the Weekend Herald.
The industry watchdog has issued a reminder to agents to protect their clients and watch out for market tactics designed to artificially drive prices down.
It follows a story last week revealing that Auckland property tycoon Ron Hoy Fong had coached investors to work in packs and place multiple low offers on properties to secure bargains.
In a coaching video distributed by the Auckland Property Investors Association (APIA), Fong also suggested investors give vendors false names and target the "seven Ds" - including deceased estates, desperate homeowners on the brink of mortgagee sales and "dummies" who don't know the value of their home.
Real Estate Agents Authority chief Kevin Lampen-Smith said Fong's advice for property investors to collude to keep prices low and target vulnerable sellers was a reminder to licensed agents to protect homeowners.
