The Boxing Day races at Ellerslie are famous for exciting fixtures and jaw dropping fashion, but this year prehistoric fashion paired with a race, minus the horses, took centre stage.
A group of people skipped the usual race day glad rags to throw on inflatable dinosaur costumes.
The t-rex race raised money for the Bowel Cancer Foundation Trust.
Organisers had hopes of 10,000 people attending today, spending around $1 million dollars on bets.
The Boxing Day races have been going for more than 160 years.
