The festival had weather contingency plans, although Mr Gorst said "no-one expected to use them" as this was the first time heavy rain had fallen on the festival in 17 years.
These involved relocating some events, however this did not deter crowds gathering for the weekend's festivities.
There were even silver linings - organisers had received great feedback about the relocation of the Gatsby Picnic from the soggy lawns on Marine Parade to Emerson St for creating a "street party atmosphere", and benefiting retailers.
While rain may have compromised some events, yesterday the streets were packed, car roofs were down, and families picnicked outside when the sun finally emerged.
With almost 90 per cent of the ticketed events sold out, Mr Gorst said he thought the festival had been a success.
"What a spirit the local people have. I don't think you could have this event anywhere else in the world."
Hawke's Bay Tourism general manger Annie Dundas said she had heard "only good things" about the festival.
"It's been amazing despite the weather, people have got spirit and were determined to still have a good time," she said.
While the economic impact the event would have was not yet known, Ms Dundas said the festival was always a huge generator for the region due to the number of people who visited, and the length of time they stayed.
In previous years, the festival had provided a $12 million investment into the region's economy.
Napier mayor Bill Dalton said it had been a "fantastic weekend".
He took his hat off to those who had worked to relocate events, and make sure everything ran smoothly.
"The work done behind the scenes to get the thing through was absolutely brilliant," he said.
Although he would always "enjoy anything to do with cars", his favourite event this year was his first time at the Beachcomber Ukulele.
"It was absolutely fabulous, it suited me right to the ground," he said.
Ms Dundas applauded Mr Pickering and Mr Gorst management of the festival: "for their first time, and in pretty awful conditions at times, they've done an amazing job."
"Bring on the sunshine next year."
