Scared and in pain, Noah was taken to Wanganui Hospital's emergency department.
"We were at the hospital for seven hours that day, and during that time I got to see a lot," Mrs Janse Van Rensburg said.
"The emergency department was extremely busy with some very serious cases, yet the staff were constantly checking on us to make sure we were all right.
"They had so much care and empathy for us."
What particularly stuck with Mrs Janse Van Rensburg was a nurse's concern for her.
"This nurse talked to me calmly, asked me if I was all right, and even offered me a cup of tea."
Mrs Janse Van Rensburg was even impressed by the seven-hour stay at the hospital.
"The staff were unsure just how badly injured Noah's elbow was, so they were really thorough in doing lots of tests. The orthopaedic surgeon was doing an operation when we came in, so we had to wait until he had finished.
"They could have just put Noah in a cast and sent him home, but they wanted to be very thorough."
Mrs Janse Van Rensburg said the staff continued to be professional and yet maintained a sense of humour. "They are humans doing their job, but they do it well."
The Janse Van Rensburgs moved to New Zealand from South Africa about 18 months ago. "We would never have had this standard of care in a public hospital in South Africa - this is what you'd expect from private health care in South Africa," Mrs Janse Van Rensburg said.
