Another damning review of the mental health sector, this time from the Auditor-General.

A new report shows some patients are being kept in mental health units for years because suitable accommodation can't be found.

Making matters worse, DHBs aren't following up with a third of patients a week after their release.

Assistant Auditor-General Mike Scott told Mike Hosking the sector faces a number of challenges.

"Things like the number of beds available and demanding higher number of beds available, things like stable accommodation being available for people so thy can be discharged to a suitable environment," he said.

Scott said there's also a lack of beds available at treatment facilities.

"We found that there is an urgent need for improvement, it's important that the services are provided to meet the needs of the local communities in particular areas," he said.

A new arena in the capital will give more Wellingtonians a chance to attend top performances.

The region's economic development agency is looking into the viability of a venue which could seat up to 12,000 people.

Promoter Phil Sprey told Mike Hosking the new venue wouldn't spread New Zealanders too thin.

He said that's because many people can afford the tickets to events but not the travel.

"The extra cost of having to pay for airfares, accommodation, extra day off work, may be something that 15% of the population could enjoy but for 85% of the local population it would become a once a year luxury," he said.

Sprey said the arena has been a long time coming and he is confident it will turn a profit.

He said it will have to cater for everything from sport to entertainment to be a viable business model.

"Being last with in with an arena type set up gives us the advantage of learning from the others and setting it up in such a way that it's true multipurpose and serves many parts of the market, " he said.

A revolution in HIV treatments could be behind a spike in diagnoses.

The number of New Zealanders diagnosed with HIV has reached a record high - with 244 people diagnosed with the sexually transmitted disease last year.

Almost 160 of those diagnosed were gay or bisexual men.

Aids foundation executive director, Jason Myers, told Mike Hosking the range of available treatment means HIV is no longer a death sentence.

But he said people, and particularly men, are looking to treatments instead of protection and prevention.

"Treatments have revolutionised the way in which HIV is perceived, changing the ways which people see the impact of an HIV diagnosis on their lives."

However Myers said the results are disappointing.

He said even though treatment has come a long way, messages about prevention haven't changed.

"It's a very simple way to prevent HIV transition, and that's to wear a condom. This does have the potential to get out of control again if we don't do everything we can."

Despite that, he says the Government still won't budge on cannabis.

Mr Joyce and Labour's health spokeswoman Annette King both spoke with Mike Hosking this morning.

"I certainly think there is a case to decriminalise cannabis. Criminalisation hasn't stopped people using those drugs," she said.

An ex-Kiwi has championed a new law to crack down on child sex offenders in Australia.

The Australian Government is cracking down on pedophiles by stripping them of their passports to stop them from travelling to South East Asia for illegal child sex.

Australia Correspondent Steve Price said there are thousands of men on the child sex offenders list who, until now, have been able to travel freely in and out of the country.

He told Mike Hosking New Zealand-born broadcaster turned Senator Derryn Hinch pushed for the new laws.

"It was the big thing, the big campaign on before the election. We've got 20,000 Australian men on the child sex offenders register," he said.

Price told Mike Hosking the law is a wordlist that hopes to protect children from exploitation.

"Up to 100 [pedophiles] a year were headed for places in South East Asia on child sex tours, anyone on that child sex offender register now will have their passport stripped off them," he said.
