concordnz: And nowhere in the Consumer Gurantees Act does it mention 'travel' or 'labour'. (hint try searching these words in the act and see what you come up with = a big fat zero)
But it does mention loss and damage https://www.legislation.govt.nz/act/public/1993/0091/latest/whole.html#DLM312823 and the OP will have lost that money if the invoice is paid.
