Infrastructure manager Jacqui Robson said there was a real push to get the trail finished in time for summer.
"Communities and individuals the length of the trail have invested a lot of energy into this project and numerous new business ventures are eager to cater for visiting cyclists. I'm confident this trail will quickly become a key attraction for tourists and locals alike," she said.
An official opening ceremony was planned for early February, probably at the Hokianga end of the trail.
Construction of the trail was divided into four stages. The first to be completed follows a 14km rail corridor between Okaihau and Kaikohe and includes an 80m-long curving rail tunnel. The trail then continues a further 34km east from Kaikohe to Kawakawa, taking in Otiria and Moerewa. The final 11km stretch east goes from Kawakawa to Opua. These sections are all grade 1-2 and suitable for all riding abilities.
The 25km stretch west from Okaihau, ending at Mangungu Mission, is the most demanding. This is a grade 3 trail and follows the Utakura River to Horeke with a 1200m section of boardwalk through mangroves on the edge of the harbour.
The cycle trail started as a Kaikohe-Hokianga Community Board project to open up the old Kaikohe-Okaihau rail corridor, championed by then board member Tracy Dalton.
