The Darren Weir-trained triple Group One winner Humidor has been given top weight of 58 kilograms in both the Caulfield and Melbourne Cups.

The former Kiwi is an unlikely runner in both races with the Gr.1 Cox Plate (2040m) and the Gr.1 Emirates Stakes (2000m) the targets for the campaign.

There were 183 horses nominated for the A$7,050,000 Lexus Melbourne Cup on Tuesday, with 34 New Zealand-bred and 10 New Zealand-trained.
