A Christchurch couple says there's no reason Multiple Sclerosis sufferers couldn't have a stem cell transplant in New Zealand.

Royce Brewer, who's had MS for 25 years, fundraised 80,000 and flew to Russia to have the procedure because it's not offered here.

An MRI scan has confirmed his lesions have decreased - he can now sleep, process information and he's not suffering headaches or vomiting.

His wife Gabby said four other New Zealanders are re-mortgaging their homes to go and have a transplant

She said that's a shame when the facilities are here in New Zealand - but are only used for cancer patients.

The couple's urging the Government to offer the treatment to MS patients so they don't have to endure financial hardship and can have the support of their families at the same time.

"There's some major breakthroughs so get on board and get excited, and help your sufferers."

She added that the government needed to "stop turning them down, and turning them away, and turning them to Pharmac's massive bucket of drugs."

The procedure is considered risky, because of the effect it has on the patients immune system.
