David Seymour has levelled a challenge to other MPs, asking them to join him in abseiling down a 17-storey-building on Auckland's Queen St.

Mr Seymour hopes the stunt, dubbed Rope for Hope, will raise $1500 for the Make-a-Wish Foundation.

"I know a few people who'd like to throw me from a ledge, but none more so than the good people at Make-a-Wish," he said.

"This is a great cause. Rope for Hope will raise funds to grant transformational wishes for Kiwi children living with critical illnesses."

Mr Seymour said he'll raise more money if other MPs join him. He's invited the entire National Party caucus because they "don't have a lot to do in Opposition at the moment", Green Party co-leader Marama Davidson because it would be a "cunning stunt", and Deputy Prime Minister Winston Peters.

"Even Winston could take the plunge. I'll help to set the ropes up for him," he said.

"With the support of my colleagues, the money we raise will help make a wish come true for a child living with a critical illness."
