Every six months the flying Rotarians meet somewhere and last weekend it was Dannevirke's first turn to host 22 members of the International Fellowship of Flying Rotarians (IFFR).
Mr Gimblett has also organised similar events in Napier and Paraparaumu.
The Gimbletts' organisation of last weekend's extensive tour of businesses and our iconic tourist spots was a winner with the visitors.
"We are all blown away," Phil Pacey, the incoming world president of IFFR, told the Dannevirke News.
"It's been absolutely unbelievable, brilliant.
"We were amazed at what we discovered when we visited RCR Energy, Metalform, Scanpower's Oringi site, the Fantasy Cave and Dave's Den.
"We have discovered some serious industry going on behind the scenes here and it's been wonderful. You can read about things, but to see them for yourself . . ."
Originally from Hastings, Mr Pacey now lives in Auckland, but his grandparents had settled at Te Rehunga and a road trip in the area had special meaning for him on Saturday afternoon.
"Graeme and Carol Gimblett have done a marvellous job in organising this visit and although only two planes flew into Dannevirke, we realise what a special place your aerodrome is. Don't ever lose it."
Mr Gimblett said the visitors were amazed by the work being done at Metalform, RCR Energy and Scanpower.
"Everyone was staggered to discover that a small town such as Dannevirke is so far ahead of others," he said.
After visiting Norsewood on Saturday evening and dinner with Dannevirke Rotarians at Oruawharo homestead in Takapau, the group went off the beaten track on Sunday.
After morning tea at Herbertville, they went cross country over Akitio Station, enjoying panoramic views of the Pacific Ocean and lunch in Dan Ramsden's woolshed at Mangaroa Station.
