The event was hosted by the new Waikato economic development agency Te Waka.
The agency, launched in late July, worked with the Matamata-Piako District Council to apply for the funding, said Te Waka chief operations officer Harvey Brookes.
Te Waka is looking to pitch 20 to 30 "high-impact" economic development funding cases to the provincial growth fund in the next three months, he said.
They would be from a short list developed from Te Waka's recent economic forum where more than 200 greater Waikato business people were encouraged to offer ideas for areas and sectors of the region that needed development support.
Even just two years ago, Waikato had received only $85,000 a year in government economic development funding, Brookes said. Aquaculture would be a strong focus of the agency's initiatives.
Te Waka was formed with the driving influence of Hamilton businessman and entrepreneur Dallas Fisher to give the region a collaborative voice when approaching Wellington for economic development funding support.
Ardern said many people thought dairy heartland Waikato was a rich region but she disagreed.
Pockets of south Waikato and Hauraki were two of New Zealand's most deprived districts, she said.
Ardern said she would like Te Aroha, Morrinsville and Matamata to become a tourist destination "triangle".
