He won in 2005 with 59.4% of the vote, National's Ken Yee only pulling in 28.2%, so Robertson looks safe once more. His electorate support is pretty much duplicated by party support. This is largely an electorate of low income Pacific Islanders, where Labour fights hard for turnout.
His most prominent role is as Assistant Speaker. Yes 21 years and that's what he gets. Nevertheless, the locals must love him. His Labour 08 profile is rather unambitious:
"I am especially aware of the need for safe communities and quality standards in healthcare and education, so that business can create wealth, the vulnerable are encouraged, and all our citizens are invited to contribute.
I will continue to be available to listen and serve, and welcome the challenges of continuing to serve Manukau."
At least he isn't claiming credit for schools, roads and the like. At least he has a profile. National's Kanwal Singh Bakshi has little hope of defeating him.
PREDICTION: Robertson's a shoo in, but he doesn't want to be in Cabinet (or isn't up to it), though perhaps what that electorate wants is a local representative and assistant full time.
