A Papamoa pub is inviting people to share a keg this Friday in the name of Australian aid.

Patrons will receive a pint in return for any donation at or above retail price at Papa Mo's from 3pm until the keg is empty.

Papa Mo's owner-operator Luke van Veen was inspired by the ‘Karma Keg' movement, which encourages patrons to choose the price of their beer based on the knowledge that the proceeds will go to charity.

The Relief Keg for Australian Bushfires event is Luke's way of doing his bit for Australia.

He will not take any money home and 100 per cent of the funds raised will be donated to the NSW Rural Fire Service.

A number of local businesses have become involved in the event, including brewing company The Island which donated a keg of Easy Lager.

Local businesses have also contributed to a raffle and barbecue aspect of the afternoon, with live music following from 5-8pm.

Luke thinks more people need to help out with the situation across the ditch and hopes this event will motivate them to donate.

'A lot of people don't feel like their $10 will do anything so they don't donate by themselves. In this setting $10 can become $1000 and if we get together and do this we can make more of a difference.”

Luke encourages people to make an afternoon of it and have some fun for a good cause, with a cold pint in hand of course.
