Andrew Nicholson still at odds with Equestrain New Zealand

Top Kiwi equestrian Andrew Nicholson remains in doubt to compete at next year's Olympics.

The 53- year-old has chosen to withdraw from negotiations to reintegrate himself into the High Performance Squad.

The six time Olympian pulled out of the New Zealand squad last year after a falling out with team vet Ollie Rynn during the World Equestrian Games in France.

Equestrian Sports New Zealand update their high performance squads every six months, Nicholson made himself unavailable for the squad named in December.

Nicholson has previously indicated that he could switch in allegiances to Britain where he's been a long-time resident.

Absence from the squad means Nicholson does not receive funding from the sporting body.

The revised High Performance Squad has little change from that named in December - the only difference being the horses that riders are considering using.

The squad being husband and wife combination of Tim and Jonelle Price, double Olympic champion Mark Todd, Jock Paget, Caroline Powell, Lucy Jackson and Clark Johnson.

The criteria for the riders and their horses is that they have shown the ability to finish in the top five individually at the 2016 Rio Olympics.
