A young Sydney poet, Sam Webster, played a significant role in the creation of 2 One Another.
"I just loved his work. It is so fresh and of the moment," Bonachela says.
"So he came into the studio for two or three weeks and just wrote and wrote. Then there was an interaction between his words and the dancers, and the poetry was also inspirational in the composing of the music, by Nick Wales."
Some of Webster's words are spoken and intertwined through the finished performance.
"It is not a narrative work at all," says Bonachela, "but it is very beautiful and open and a very emotional journey."
It is also frequently described as spectacular and a "visual feast for the audience", with a subtly synchronised backdrop of pulsing LED lights, designed by Tony Assness, linking to the sound and movement on stage. Assness also designed the striking costumes.
Sydney Dance Company was once a regular highlight of Auckland's dance calendar, but this is its first visit in more than a decade.
"The company has a beautiful history," Bonachela says.
But, by 2007, it had lost its celebrated shine and was sinking under the weight of on-going financial difficulties. Exhausted by a protracted funding war with the federal government, its brilliant and popular founders, Graeme Murphy and Janet Vernon, finally bailed.
A young German-born star of the contemporary dance world, Tanja Liedtke, was appointed as Murphy's replacement. But just before she was due to take up the post she was killed in a tragic early morning accident involving a rubbish truck.
Bonachela's subsequent appointment caused more than a little consternation among the fans of Murphy's more lyrical and narrative choreographic style. Bonachela was already known as a "movement junkie", a creator of abstract and intensely physical works -- and for his successful involvement with the dance spectaculars of a series of pop stars, including Kylie Minogue, which was not seen as a positive in some quarters.
But Bonachela, who was a friend of Liedtke from their shared days at the Rambert dance company in London, was encouraged by her partner to accept.
Then, unfazed by controversy, ever-enthusiastic and a fast mover out of the blocks, he promptly fired seven of the company's existing dancers.
But his judgment has proved to be correct.
The six years of his tenure so far have brought six years of outstanding success: a doubling of audience numbers, sell-out shows, critical acclaim at home and abroad, and an instant financial turnaround.
Bonachela has recently signed a contract that will see him in command for the next six years and for the company's important 50-year celebrations in 2019.
