Mr Abramov has been reported as owning the superyacht Triple Seven, a sleek and modern 67m boat with a cinema, gym and jacuzzi, which has visited Auckland twice.
The walkway will enable the billionaire and guests to mount deep-sea fishing expeditions from Helena Bay and tie up the boat once their catch is on the BBQ.
The structure is understood to have cost about $1 million. For the pathway, workers laid a base of gravel on the existing rock, then built a base shape into which they tipped cement. It was sculpted by hand and waterblasters to get a natural shape as close to natural rock along the foreshore as possible.
Experts say these were the same techniques used to create the natural-looking environments created by builder NZ Strong at Auckland Zoo where new precincts were developed to showcase New Zealand.
The Department of Conservation tried to stop Mr Abramov building the long winding concrete path across coastal rocks and jutting out into the bay, saying it was unnecessary. But Mr Abramov beat off the state, although he had to meet a number of conditions.
Chris Seel, project manager, said replica rocks were used to make the walkway discreet. He said the same techniques had been used at Auckland beaches at Kohimarama and Mission Bay.
