In the early days as an MP he enjoyed a golden run, finding favour in Wellington and also forming a good partnership in "Backing the Bay" with former Napier MP Chris Tremain.
However, in recent years his fortunes seemed to dip with the National Party hierarchy and also he seemingly lost his way on local issues, especially the Havelock North kura. Either way, his departure will make next year's Tukituki election very interesting indeed.
The Labour Party candidate, Anna Lorck, who was beaten by Mr Foss last time, must feel like she has been given an early Christmas present.
She has a lot of work to do to be more appealing to voters, but she has got a grasp on the local issues and it is easier to take a seat that is not occupied by an incumbent MP.
The crucial thing will be which candidate National puts up in Tukituki. They will have to go local and who knows, they may even consider shoulder-tapping a current mayor.
Watch this space. It will make for a very interesting contest.
