Unlike in 2010, when he led a five-strong field to a 1700-vote victory over C&R candidate and current National list MP Alfred Ngaro, Ms Krum is now his only challenger.
By contrast, all's quiet in the local board's Maungakiekie subdivision, in which the three members of Maungakiekie Team were re-elected unopposed although keeping billboards up to remind voters who's representing them.
But Ms Krum, who managed Mr Ngaro's campaign and was president of United Future before joining National in 2009 and becoming its deputy Auckland regional chairwoman, jests about forming a "10 per cent club" among many she finds paying the council's maximum capped rates increase.
In her latest of three election pamphlets, in which she labels her rival a "career politician" of more than 25 years' standing, the 42-year-old businesswoman and mother of two also lambasts the council's Unitary Plan intensification blueprint with its proposed allowances of six-storey housing around the town centres of Onehunga, Royal Oak and Panmure - and eight storeys in Glen Innes - as too intense.
An outwardly unflappable Mr Northey, aged 68 but training for the Onehunga Bay half-marathon in 10 days and portraying courage under fire despite being out-gunned almost two to one by Ms Krum's campaign billboards, says he has worked hard with local board chairman Simon Randall and deputy Bridget Graham to keep intensification from character areas such as Grotto St and Normans Hill Rd in older parts of Onehunga.
Calling Ms Krum's efforts "very much a National Party campaign", he blames the Government's insistence on a unified rating system for a wide variation in rates from the regional average of 2.7 per cent.
As for intensification proposals, which could allow developments of up to four storeys across much of the ward and six storeys around town centres and railway stations such as Onehunga's, he says:
"That's the only way people are going to be able to afford to buy in there."
He rejects a right-wing blogger's portrayal of him as a "tired old war-horse", insisting he is fighting fit and asking what's wrong with a battle-hardened politician who has campaigned successfully for facilities such as the new Oranga community centre and a music and arts centre going up soon in Glen Innes.
"It's funny that nobody seems to mind career teachers or policemen - they usually get better as they learn more and get more experience and I think I've drawn on that to help solve some of the more complex problems facing the Super City," says Mr Northey, who chairs the council's accountability and performance committee.
Ms Krum, ranked 69 in the last general election as a National list candidate, acknowledges having tried three times to win selection by the party as an electorate MP but says she is now focused on becoming a councillor and "having a great term", short of making a career of it.
Although her first pamphlet was delivered to 23,000 homes in an afternoon, she denies relying on party resources, thanking more than 100 volunteers befriended through her community work as head of a local charity and chairwoman of Ellerslie School's board of trustees.
Although the local board will remain a C&R-free zone, she believes her wide community connections will ensure she is not stranded on the council without grass-roots support.
