Macaques are being phased out of the region, they are now, at least in ZAA zoos, in relatively low numbers, with most members of each species clustered at just one zoo, with breeding prevented. For example, all the bonnet macaques are kept at Auckland Zoo. As they are reasonably long-lived species, they may persist in the region for a while, but many have been transferred to non-ZAA zoos. One of the reasons given was the risk of Herpes transmission, which was a pretty weak argument I thought. Clearly the six or seven species in the region couldn't have all been maintained, but one (or two) could easily have been. Especially one like the Sulawesi Macaque, which ticks all the ZAA boxes (endangered, Asian).
