From central Wellington, take the northern motorway, driving around the harbor toward Lower Hutt, and follow the signs to Wairarapa. Once on this route, you head over the Rimutaka Hills and arrive in Featherston, the southernmost village in Wairarapa, around 1 1/2 hours later.
If you're entering the area from the north, it takes 3 hours from Napier and 1 hour from Palmerston North to reach Masterton. Flying to Martinborough from Wellington by helicopter takes just 15 minutes.
In Masterton, the Masterton Visitor Centre, corner of Dixon and Bruce streets (tel. 06/370-0900; fax 06/378-8451; www.wairarapanz.com), is open daily Monday to Friday 9am to 5pm, and weekends 10am to 4pm, with extended hours in summer. If you don't intend to drive the extra 30 minutes north from Featherston/Martinborough, check out the office at 18 Kitchener St., Martinborough (tel. 06/306-5010). It's open the same hours.
