Fieldays fever has begun and motorists are warned of heavy traffic and delays.
The queues for Fieldays are expected to start from 6am today. Those who bought tickets online will have access to a separate entry and discounted prices for two or more tickets.
Fieldays was launched last night at Waikato University.
Minister of Agriculture David Carter will also officiate at a brief ceremony on the site at 12pm today.
Motorists are being urged to use State Highway 3 as a possible quicker alternative to State Highway 1 and to be aware of more traffic on the roads.
