Having read the posts here and other forums, seems like the part about subscribing to an event is rather tricky. I gather that understanding lifecycle hooks and how promises work is important to getting around the problem. The following works if you want a second page to be able to subscribe to a published event on an existing page:

this.navCtrl.setRoot(NextComponentPage, Parameters).then(()=>
{
    this.events.publish("user:created", userdetails);
});
