Prince William is taking a break from wedding preparations to tour areas of New Zealand devastated by February's Christchurch earthquake and to visit families who lost loved ones at the Pike River Mine in Greymouth.

Prince William walked through central Christchurch, which still remains inaccessible to the public to see firsthand the impact of the 6.3-magnitude earthquake which hit on Feb. 22 and killed at least 155 people.

The scale of it is unbelievable, he said.

He took the time to speak with members and family of the Urban Search and Rescue team in Christchurch as well as personnel at the Emergency Operations Centre and city fire fighters. Prince William will be in New Zealand until March 19.

He will then travel to Australia for three days to visit regions affected by floods.

It's a busy time for Prince William as he is preparing for his April 29 wedding to Kate Middleton in Westminster Abbey.
