A sold-out annual benefit dinner to raise money for local medical research has surpassed previous fundraising efforts.

The dinner was organised and hosted by the Otago Medical Research Foundation.

It generated about $75,000.

That's a significant increase on last year's $58,000.

And it's more than double the $35,000 raised in 2013.

The money will be used for research projects and summer scholarships in Dunedin.

People have already started registering for next year's dinner.
