Are there others here who would support a reduction in the TTL for at least .co.nz ?
Yes, something like four hours would be a reasonable compromise between load and practical requirements. In theory a TTL of one day is not an issue if Name Servers are changed to another server with an identical zone file. In practice the reason for changing Name Servers is usually "something is broken" e.g. a dispute and the provider has dumped the zone. The problem being that caching resolvers will cache the fact that a zone doesn't have any usable Name Servers (Hmm, remember Microsoft), so it takes 24 hours before a broken zone will burst back in to life. Far to long for a business.... a TTL of 4 hours means thay can be back online by 3pm.
