The track was broken in over Easter by hundreds of cyclists involved in the inaugural New World Tour de Wakatipu, and is one of the final missing links of a historic Wakatipu trail connecting Queenstown and Arrowtown.
From Arrowtown, an existing track along Manse Rd leads walkers to the new Millbrook section of the track.
From there, it skirts the new Millbrook driving range and then runs alongside The Avenue to Millbrook Village Centre.
From the resort centre, the trail meanders alongside Mill Stream and through copses of trees, then goes south, crossing the new Coronet Nine golf course before leaving Millbrook.
A new trail then leads down to Speargrass Flat Rd and along Rutherford Rd to the Lakes Hayes Loop Track.
Millbrook property development manager Ben O'Malley said it was a "spectacular" track which started and finished at vantage points looking towards Lake Hayes and the Remarkables and provided beautiful vistas over the new golf course.
Mr O'Malley said Millbrook had worked closely with the Queenstown Lakes District Council to integrate the track into the resort's master planning and the two parties had negotiated a stakeholders deed.
As a result of that deed, Millbrook would vest 3.14ha of its land to the council and the community for recreational use, Mr O'Malley said.
"That land, known as the Arrowtown Corner, is capable of taking a rugby field and a cricket field with all the parking required, which will endow the Arrowtown community with additional reserve land."
Millbrook marketing director Kim Carpenter said the new track would appeal to those who wanted to see more outdoor recreation options available at the resort.
"Allowing access to the hiking trails at Millbrook will be ideal for locals, visitors and guests of the resort to see a portion of Millbrook that they've never seen before."
Mr Carpenter said track users were encouraged to park near the Millbrook village centre where they could link to the Lake Hayes track, on a Millbrook via Lake Hayes return trip of around 16km.
"If they want a shorter walk or bike, it's a 5km round trip to Arrowtown and back."
Mr Stevens said the Wakatipu Trails Trust was dedicated to establishing a world-class network of trails in the Wakatipu.
