It's the XU1 I remember him for. I'm sure I knew his co-driver - was it John Reid?
John Reid was Co-Driver in the Escort TC, think the XU-1 was after that so quite likely as Ian Dickson was no longer in Gore or 'down south' in that period, XU-1 came to grief on a sprint around 'old SH-1' around lake waihola IIRC
