He was a rugby commentator for Sky Sports during the All Blacks' test against Samoa in early 2015 — a fixture he had vocally campaigned for while hosting Campbell Live.

[3] He graduated from Wellington College[4] and then from Victoria University with a Bachelor of Arts degree with Honours in English Literature.

Campbell started broadcasting at Victoria University's Radio Active as a student where, as "Sparky Plug", he provided humorous "alternative rugby commentaries" during All Black games which he now describes as "unbelievably rude" and "grossly defamatory.

[6] He read the three-minute news bulletins on the hour for RNZ, and then moved to TV3 in 1991 as a general reporter in their Wellington newsroom.

In 2002, Campbell was interviewing Prime Minister Helen Clark about the issue of genetically modified corn in New Zealand, dubbed 'Corngate'.

[9] The Broadcasting Standards Authority (BSA) later ruled that the infamous "Corngate" interview was unbalanced, unfair and lacked impartiality and objectivity.

[16] He subsequently moved to TVNZ, becoming a roving reporter across the company's news and current affairs output, as well as an occasional fill-in presenter on 1News.

[29] In 2019, while filming a story in Samoa with producer Adrian Stevanon for TVNZ's Sunday programme, Campbell was awarded the chiefly title Toleafoa by Samoan Head of State Tuimalealiifano Vaaletoa Sualauvi II.
