Auckland, Nov 16 NZPA - Free buses are being arranged to help those wishing to attend a march in Auckland calling for citizens-initiated referenda to be binding.

The march, to be staged along Queen St on Saturday afternoon, is being sponsored by Auckland businessman Colin Craig after he was upset the Government ignored the result of this year's referendum against Sue Bradford's child discipline law.

Mr Craig said three citizens-initiated referenda in the last 10 years had achieved overwhelming support from the public but had been ignored by governments.

These included 1999 referenda calling for a maximum of 99 MPs and for a tougher attitude to criminals.

Mr Craig said he hoped the march would be New Zealand's biggest ever, which would mean 50,000 to 70,000 marchers.

"I don't want to speculate on the numbers," he said. "But can we do that? Yes, we can. It is up to New Zealanders."
