Barry Leigh Fitzgerald (63), of Melbourne, was charged with careless driving after the December 3 smash at Closeburn.
A Wellington-based police media adviser said in an emailed statement today that Fitzgerald had completed diversion.
She refused to say what the conditions of his diversion agreement were.
The 1994 car was part of the inaugural Epic New Zealand Road Tour, which pays tribute to the brand's Kiwi founder Bruce McLaren.
A convoy of 31 McLarens from around the world travelled from Auckland to Queenstown.
