Do I need a Care Plan to move into rest home?

No you don't need a Care Plan to move into a care home but one will be developed with you either before or on your arrival. 

A Care Plan details how care will be delivered to you when moving into a care home. It is created based on the results of your interRAI assessment, which is a requirement for moving to care (unless you are a fully-private payer). You, your family/whānau and your extended care network can all be involved in the creation of this plan, so that you are able to make informed decisions about care.

Care plans should be reviewed every six months or if you have a change in circumstances – i.e. a health issue.
