Top businessmen and women from throughout New Zealand are coming to Dunedin to give advice to budding entrepreneurs.

They're visiting for the fourth annual Startup Weekend, being held at Otago Polytechnic at the end of the month.

It'll see entrepreneurs, mentors and investors gather locally to launch new businesses.

Organisers say the non-profit event is a chance for locals to start businesses in just over two days, with support from experienced professionals.

Those attending will be invited to pitch business ideas to judges and investors at the end of the weekend programme.

The event's sponsored by the polytechnic as well as the University of Otago and several other local organisations.
