Only one Rover came to New Zealand in 1985. I can't remember who co-drove with Walkinshaw. I have a photo of the car somewhere so will track it down. It was white, and sponsored for its Kiwi races by NZ magazine 'More'.
The following year (January 1986) Walkinshaw brought two Rovers, painted brown and sponsored by NZ chocolate company Whittakers (Peanut Slab). Have to say, the brown paint didn't look too good on those cars, not that it looks much good on anything else!
They were lovely cars, sounded beautiful, but didn't live up to expectations on either occassion on the tight, bumpy Wellington street course. I guess they were happier on the fast sweeping European circuits. Interestingly, TWR brought two Jaguar XJS' out in January 1987, he rcieved special dispensation for them to compete, and they went extremely well.
One of the Bastos Rovers now resides in New Zealand, in the South Island, and competes in Historic events. The Bastos livery is completely original. Interestingly, its actually hand painted, not stickers! Heres a photo of it from Ruapuna this year:
