plot.zoo uses the axis functions in R's classic graphics but zoo also offers lattice graphics as well via xyplot.zoo. Just changing plot to xyplot may be sufficient for your needs:

library(zoo)
library(lattice)

# create test data
z <- zooreg(1:83, start = as.Date("2009-04-01"), deltat = 7)

xyplot(z)

Note that there are further examples in ?plot.zoo and ?xyplot.zoo as well as the three vignettes that come with zoo. In those places you can also find find examples of a different approach showing how to use the axis function of classic graphics together with plot.zoo for highly customized axes.
