Passionate atheists in New Zealand are copping abuse for their plan to put giant stickers on the sides of buses advising people to stop worrying because there is probably no God.

The atheists want public donations so they can put the stickers on the side of buses in Auckland, Wellington and Christchurch.

The stickers read: "There's probably no God. Now stop worrying and enjoy your life."

When similar stickers were put on London's trains and buses earlier this year, many religious groups were far from happy.

New Zealand spokesman for the atheist bus campaign, Simon Fisher, told Radio New Zealand that he has received a number of abusive emails.

"Quite nasty ones, along the lines of, 'You're going to hell'," he said.

But Mr Fisher says he is not worried.

"For one, I don't believe in hell, so it's not too bad."

He hopes the stickers spark lots of fiery debate and wants them in place by February.
