There are a growing number of Australians running their own self-managed superannuation funds (SMSF).

If you're one of them, then listed below are a few ASX exchange-traded funds (ETFs) that could be worth considering as new additions to your SMSF.

Let's see what they offer and why they could be top picks for a balanced investment portfolio:

BetaShares Diversified All Growth ETF (ASX: DHHF)

The first ASX ETF to consider for a SMSF is the BetaShares Diversified All Growth ETF. This ETF was recently named as one to buy by the team at BetaShares. It highlights that this fund gives investors easy access to ~8,000 large, mid, and small cap stocks from Australia, the United States, developed markets, and emerging markets. It believes this gives the fund high growth potential, which could make it suitable for investors with a higher tolerance for risk. This means those towards the beginning of their SMSF journey, rather than investors that are nearing retirement.

Betashares Global Cash Flow Kings ETF (ASX: CFLO)

A second ASX ETF to look at is the Betashares Global Cash Flow Kings ETF. It has also been tipped as one to look at by the team at Betashares. The fund manager points out that companies that generate high levels of free cash flow have a tendency to outperform the market over the medium to long term. That's exactly what you want for a holding in an SMSF – an investment that will compound over the years and grow your wealth. Among its holdings are tech giant Alphabet (NASDAQ: GOOG) and payments behemoth Visa (NYSE: V).

iShares Global Consumer Staples ETF (ASX: IXI)

A third ASX ETF to consider for an SMSF is the iShares Global Consumer Staples ETF. It gives investors exposure to many of the world's largest consumer staples companies. This could make it a great option for investors that are towards retirement age. That's because consumer staples companies are generally regarded as low risk options that tend to perform well whatever is happening in the global economy. Among the fund's holdings are global giants Coca-Cola, Nestle, and Unilever.

VanEck Vectors Morningstar Wide Moat ETF (ASX: MOAT)

Finally, potentially a great option for an SMSF is the VanEck Vectors Morningstar Wide Moat ETF. It focuses on buying companies that are fairly valued and have sustainable competitive advantages. This focus appears to work wonders given that it is the same strategy that Warren Buffett has used for decades with Berkshire Hathaway (NYSE: BRK.B). You only need to look at how much he has outperformed the market to see this. It is also worth noting that this ETF is outperforming the market over the past 10 years with a 16.4% per annum return.
