The state dedicated a new $2.5 million dock at Keehi Small Boat Harbor Wednesday.
The new Pier 100 was built as part of the state's Recreation Renaissance.
The old pier was badly deteriorated and had to be demolished in April of last year.
Harbor improvements have also been made at Ala Wai, Haleiwa and Waianae.
The state says there is much more work to be done.
"Look at our state's parks and recreational spaces compared to any place else they travel in this country, the embarrassment will start to wear on them after a while. And as legislators, they will have to answer to the public why did you let it go on so long," said Governor Linda Lingle.
The new dock was made using corrosion-resistant materials.
Two other docks are also being replaced, with work scheduled to be completed sometime next year.
