Superannuation advertisement was a 1997 marketing campaign for the New Zealand Superannuation Services (NZSS). The advertisements in the campaign featured Tom Baker as the Fourth Doctor in the TARDIS, which (along with the Doctor Who theme) was licensed from the BBC.
In his autobiography Who on Earth is Tom Baker?, Tom Baker wrote, "'Would you like to go to New Zealand to do a commercial?' That's the sort of question an actor likes to hear from his agent in freezing mid-January." He arrived in Auckland on 18 January and returned to the UK on 29 January; recording took place from the 21st to the 23rd in Studio 601 in Newmarket, Auckland, and on the morning of the 22nd on location at the rim of a crater on Mount Eden in Auckland.
- A behind the scenes feature of the advertisement was released titled Behind the Scenes of Tom Baker's Return.
- This was the first on screen appearance of the Fourth Doctor since Dimensions in Time.
- The end of the advertisement featured the phrases "TIME IS EVERYTHING" and "0800 - TARDIS" underscored by "827347". This was a joke way of advertising their telephone number 0800 827347.
