Former jockey Michael Clarke, who won the cup on At Talaq in 1986, accompanied the cup as a tour ambassador.
Tour manager Joe McGrath said the tours were about celebrating "the people's cup" with the people.
"We're very committed to providing community engagement," he said.
The Victoria Racing Club received 70 applications for the cup to visit and Wairarapa was one of 34 chosen.
He said 42 horses bred in New Zealand have won the Melbourne Cup.
Mr Clarke said the race has grown since his day, and is strongly promoted around the world.
"There's so many great jockeys who haven't won the Melbourne Cup. The jockey that wins it, he's in the right spot, right time, right horse."
Mr Clarke said he has also won the Japan Cup but the Melbourne Cup was "the highlight of my racing career".
Tauherenikau's Jubilee convenor Graham Hodder said the club had hoped to get the cup for a race day in October but the timing wasn't suitable.
"Our brief was to give as many people as possible a chance to see the cup. It's a once-in-a-lifetime thing it's the first time I have seen it."
The cup also visited the Tin Hut, Tauherenikau, Pukemanu Tavern in Martinborough and the Kuripuni Sports Bar in Masterton over the weekend.
