Work will begin next week on the upgrade of the Winter Gardens at Rotokawau Virginia Lake.
Formally known as the Centennial Winter Gardens, they were opened in 1940 to mark 100 years since the signing of the Treaty of Waitangi.
From Monday visitors to the Winter Gardens will enter through a signposted alternative access while the entrance way is upgraded.
Project officer Debbie Anderson said the alternative access would be used from Monday to Friday, with normal access available during the weekends.
