Then CRL CEO Dr Sean Sweeney said: “Dame Whina’s legacy is one of determination and the importance of working together, values that fittingly apply to this project and our journey ahead to build a world class railway for Auckland.

On 13 February 2020, spades in the ground at the sod-turning ceremony cleared the way for work to start on driving 66 concrete piles between 38 metres and eight metres long into the ground to support the curved-shaped retaining wall 127 metres long and 25 metres high.
The portal took 10 months to build. When completed, it became the launching pad for the TBM.
