Redirect to other page in ionic framework v3

I am new to ionic framework. I am trying to redirect to other page on button click in ionic framework version 3. I did not get enough source on this. I tried location() and go() functions but it did not work.

This is my code in newpage.html :

<button ion-button block (click)="click()">Click me</button>

This is my code in newpage.ts :

  click() {
  this.go('/HomePage');
  }
