With three laps remaining the three Kiwis opened up a gap on their rivals from across the Tasman Sea but with a little under two laps to go it was Willis who swept to the front.
At the bell, Willis held a five metre lead from Zane - with Jake now out of the race. The New Zealand half-marathon record holder briefly rallied but the 2014 Commonwealth 1500m bronze medallist responded and amid a pulsating atmosphere he claimed the sweetest of race wins a little under two seconds shy of his PB for the distance.
"You could see the Robertson's were working together and I kicked a lot further out than I wanted," admits Willis, 31. "It made it a grind, but it was exciting and I was just thankful I crossed the line first."
"It is fun to travel the world but there is nothing better than staying on your auntie's couch eating some local grub and running in front of a really boisterous crowd. For an event that has been organised in only three months it was just a fantastic turn out. I really hope that is becomes an annual event in what it New Zealand.'
A disappointed Zane, who has struggled with a calf problem since setting his New Zealand half marathon record and was racing in New Zealand for the first time for eight years, said: "I found the pace quite easy but I haven't worn spikes since last September and I've only been back training for five days. I don't like to make excuses but I wasn't at full fitness.
"The crowd were amazing. I had a lot of support. It was so awesome to see the kids come out here just like we used to watch Nick in the past. It was great to be back."
