Dessert will be familiar to the domestic goddess as it is one of her own recipes, a dark Ghana chocolate mousse from Whittaker's with chive cupcakes and a lemon-curd tart.
The event was hosted by Newstalk ZB's Kerre McIvor, with live music by Dave Dobbyn and an interactive Q + A with Lawson.
She spoke about her food and business successes, and those attending were be given a copy of her latest cookbook Simply Nigella: Feel Good Food to take home.
