West Auckland boat manufacturer Southern Spars has declined to comment on speculation the company is creating three huge masts for Jeff Bezos' super yacht.
The Herald understands Avondale-based Southern Spars is working on a high-tech mast solution worth tens of millions of dollars for the world's richest man and founder of e-commerce giant Amazon.
While Southern Spars confirmed it was working on a "significant project", a spokesperson denied this was linked to Bezos' yacht.
Pressed about the project, a spokesperson for the company, said: "We deal with the world's wealthiest." He would not comment further.
The Herald understands Southern Spars is bound by a contract in which it can not legally talk about the arrangement.
