"For the folk who work Tuesday to Saturday, or Wednesday to Sunday, they miss out on the Monday holidays. This bill won't solve that problem. But we will get a chance to hear from people on a wide range of issues. Clearly, people think this is a sensible idea."
The Bill was not going to impose a burden on employers and was not fiscally irresponsible, Mr Clark said.
Information he received under the Official Information Act suggested there would be benefits to the economy from the Monday-isation of the holidays.
"One of the industries that will benefit is domestic tourism. Prime Minister John Key is the Minister of Tourism but he is the Grinch opposing this bill.
"This is one plum thing he can do for the tourism industry that doesn't cost a lot of money yet he is not supporting the very industry for which he is Minister," Mr Clark said.
The costs incurred by Monday-ising the de-facto national days were already accounted for by employers. There was no reason that Christmas Day, Boxing Day and January 2 should be treated any differently than Anzac Day and Waitangi Day, he said.
