Mr Gliddon said the project team and tangata whenua had been working together and had protocols in place in case koiwi (human bones) or taonga (objects that relate to Maori culture, history or society) were found.
"We understand the importance of the items we find and value our relationship with tangata whenua who are helping us manage the process."
The historical display can be viewed at the TEL Information Centre which is open to the public Monday to Friday from 9am to 4.30pm.
There are also new displays showing the latest TEL construction progress images which are updated each month.
The Tauranga Eastern Link, which is expected to be completed in 2016, is the biggest roading construction project ever undertaken in the Bay of Plenty.
The link is to run from Te Maunga, near Baypark Stadium, to the existing junction of State Highway 2 and State Highway 33 near Paengaroa. It will be made up of 17km of new road and 6km of the existing state highway will be upgraded.
