The 3-hour drive south through the Waikato into the volcanic heartland — with detours to Hobbiton and Waitomo if you have time.
Head south from Auckland on the Southern Motorway (SH1). The first hour is motorway through South Auckland and into the Waikato — flat, fast, and not particularly scenic. The landscape opens up as you pass Huntly and the Waikato coal power station on your left. You'll reach Hamilton in about 1.5 hours.
New Zealand's fourth-largest city straddles the Waikato River. Most people drive straight through, but if you want a break, the Hamilton Gardens (free) are genuinely world-class — themed gardens from Italian Renaissance to Japanese, Chinese to Tropical. Allow an hour. The city also has good cafes along Victoria Street if you need coffee.
If you're heading to Hobbiton Movie Set, the turnoff is at the small town of Hinuera, south of Hamilton. Follow the signs to Matamata and then to the Shire's Rest cafe where tours depart. Hobbiton tours run approximately every 30 minutes and take 2 hours. Book ahead — this sells out. After Hobbiton, you can continue directly to Rotorua (45 minutes) or loop west to Waitomo first.
The "Corrugated Iron Capital of New Zealand" — a quirky small town with buildings shaped like animals (look for the giant corrugated iron dog and sheep). Worth a 15-minute photo stop and a coffee at one of the cafes. From here, SH5 branches east toward Rotorua through rolling farmland and native bush.
The sulphur smell hits you before the town does — that's the geothermal activity. Rotorua sits on top of one of the world's most active volcanic areas and the steam, mud pools and hot springs are everywhere. Check into your hotel, then head to Eat Streat on Tutanekai Street for dinner — it's the main restaurant strip. For a first-night activity, the Polynesian Spa (hot mineral pools on the lakefront, open until 11pm) is hard to beat.
