Core Composite's raison d'etre over the years has been to help make boats for Ellison/Oracle yacht races - particularly for America's Cup campaigns.
Its only business, according to its 2009 annual report, was "assisting its parent company in challenging for the America's Cup". Oracle Team USA won the 2010 race series and then caused widespread despair in New Zealand by coming from seven points down in the 2013 cup to beat Team NZ.
However, Ellison, Coutts and their boat lost to New Zealand last year in Bermuda. And Coutts, who is Oracle Team USA chief executive but led Team NZ to two America's Cup victories in the past, said they wouldn't have a boat in the 2021 series in Auckland.
In 2014, Core received a three-year Callaghan Innovation Growth Grant, allowing it to claim a portion of its R&D expenditure - normally between 20 and 40 per cent. Its 2017 annual accounts show these taxpayer-funded grants were worth $2.5m in the two years 2016-2017. Callaghan has now extended the grant to June 2019.
Core didn't reply by publication deadline to BusinessDesk's request to talk about what it will do with the next tranche of Callaghan R&D money.
However, in 2015 it said it was diversifying into composite materials and tooling - beyond racing yachts. Its website mentions prototypes for the Auckland harbour bridge SkyPath clip-on as an example, but accepts the America's Cup is "never far from our minds".
Previously vocal Labour Party critics of the grants are staying mum on the issue. Asked in 2015 about taxpayer funding being used to help an offshore-based America's Cup rival, Labour's then sports and recreation spokesman Trevor Mallard said Kiwis would be "horrified" to know they were backing Oracle and Larry Ellison.
Now Speaker in the Labour-led government, Mallard wasn't commenting on why his government was continuing to fund Core Builders Composites.
And his colleague, Sports and Recreation Minister Grant Robertson - also Finance Minister - didn't respond to BusinessDesk either. Callaghan Innovation didn't respond by publication deadline.
Meanwhile, it's all go for the 36th America's Cup in Auckland, with the Environment Court yesterday granting resource consent for the bases and associated infrastructure and activities.
