Wellingtonians are being called on to help create their city's very own dumpling.

House of Dumplings owner Vicky Ha is creating both a city and sea dumpling to help raise funds for Museum Wellington City and Sea.

She's offering a $5 voucher for every 500 grams of home grown veges people donate.

"I always want to try to promote people growing vegetables at home and this is what we want to do, we're going to put these two together and make this work."

The dumplings will go on sale next Monday.
