This week on Capital Letter with Georgina Campbell: A mysterious long tunnel that was mentioned on the contents pages of heavily redacted documents won't see the light of day in Wellington's $6.4 billion transport plan.

A long tunnel was not part of Let's Get Wellington Moving's (LGWM) recommended programme of investment, nor the package that was endorsed by the Government.

But all of a sudden it was being talked about behind closed doors earlier this year when alternative projects were being planned.

But LGWM Governance Reference Group chairman Daran Ponter told the Herald the long tunnel had been considered and rejected because the cost is eye-watering. 

Nick and Georgina also talk parking tickets and a $ 3.1 billion cash injection for Wellington transport from Waka Kotahi.
