"The regional council is mightily placed to provide leadership for the region. We've done an excellent job in promotion tourism and business development but more can be done."
The former MP said Hawke's Bay needed to take advantage of being in a "very strong growth period" and use the opportunities available.
The region's fundamental industries, "across the board", are the strongest he had seen in 20 years. Although there had been problems in apples and horticulture, they, and other industries such as viticulture, beef and sheep farming, were "in good shape".
"The biggest challenge for the regional council is to recognise fully what is happening in terms of growth we're seeing and to work together to maximise benefits for the region."
However, Mr Barker said that had to be done with the environment in mind.
"It's about how we continue to grow without compromising our fundamentals, which is the fertile soil of the Heretaunga plains."
If re-elected, Mr Barker's other areas of focus would include riparian planting, restoring fish life and improving water quality.
"In local government there is no end state ... there's always going to be work to be done," he said.
"There is plenty to do ... and I want to get on with it."
