"We had a lot of contact from other farmers around the country," Lynley said. "Even rural community groups got back to us and said they were going to do it as pot luck sort of thing, or hosting a big barbecue.
"We didn't expect it would go over so big."
Listen to Rowena Duncum's interview with Lynley Wyeth on The Country Early Edition:
As to their own invitation to a townie family to come and have lamb for dinner at their farmhouse on Thursday, there was no shortage of people wanting to tuck in.
"We had hundreds say they'd love to come," Lynley said.
When the Wellington couple they selected had to pull out because of a clash of commitments, the Wyeths picked a young couple from Masterton with a six-month-old baby. The newly-appointed principal of a local school has also been invited.
The forecast says Thursday's weather will be foul, so Lynley has ditched her original idea of lamb steaks and salad in favour of a trio of steaks entrée ("naked", with salt & pepper, and with Moroccan seasoning), followed by a rack of barbecued lamb served with roasted vegetables.
The guests will work up an appetite joining the couple and their kids to check out the farm's streams, woolshed and flocks.
Federated Farmers Meat & Wool Chairperson Miles Anderson congratulated the Wyeths on their initiative. "It's a great way of fostering a better understanding of what farming the New Zealand way is all about - not to mention promoting our tasty and succulent lamb," he said.
Lynley said Beef & Lamb NZ is investigating picking up the 'Invite a Townie to Dinner' concept for future National Lamb Days.
